DON’T MAKE THIS MISTAKE!!!

DAMAGE TO YOUR BUFFERING RECOIL SPRING GUIDE AND YOUR HI-POWER WILL RESULT!

USE GUIDELINES & INSTRUCTIONS

BHSpringSolutions / EFK Fire Dragon

Buffering Recoil Spring Guide Rod Assembly

DETERMINE OPTIMAL BUFFERING SPRING:

IMPORTANT NOTE: DO NOT USE ANY OIL OR LUBRICANTS ON THE PARTS OF THE DEVICE UNTIL AFTER THESE USE GUIDELINES & INSTRUCTIONS, AND FULL ASSEMBLY, HAVE BEEN COMPLETED.

UNLOAD A HI-POWER PISTOL AND TRIPLE CHECK THAT THERE IS NO AMMUNITION IN THE FIREARM. MAGAZINE MUST ALSO BE EMPTY. THERE SHOULD BE NO AMMUNITION IN THE ROOM WHEN COMPLETING THESE USE INSTRUCTIONS.
WITH NO MAGAZINE INSTALLED, RACK THE SLIDE USING YOUR TRADITIONAL RECOIL SPRING GUIDE ROD (NOT THE BUFFERING RECOIL SPRING GUIDE ROD). NOTE THAT WHEN THE SLIDE IS FULLY RACKED TO THE REAR, THERE IS AN AUDIBLE METAL-TO-METAL “CLICK” WHEN THE SLIDE ARRIVES AT ITS MAXIMUM REARWARD TRAVEL. THAT “CLICK” IS THE SLIDE / FRAME “COLLISION” THAT WILL BE BUFFERED BY THE BUFFERING RECOIL SPRING GUIDE ROD.
REMOVE SLIDE FROM FIREARM. REMOVE RECOIL SPRING AND RECOIL SPRING GUIDE ROD FROM SLIDE.
REMOVE BUFFERING RECOIL SPRING GUIDE ROD FROM PACKAGING BAG – NOTE THAT NO BUFFERING SPRING IS PRE-INSTALLED, AND THE END CAP IS NOT PRE-INSTALLED IN THE UNIT.
END CAP IS SHIPPED IN THE HEAVY BUFFERING SPRING BAG. REMOVE THE HEAVY BUFFERING SPRING AND END CAP FROM HEAVY BUFFERING SPRING BAG.
NOTE: ALL BHSS BUFFERING SPRINGS HAVE ONE END THAT IS A “CLOSED COIL” (FLAT END) AND ONE END THAT IS A “CUT COIL”. INSTALL THE SPRING WITH CLOSED COIL END ENTERING THE HOUSING FIRST.
HAND-TIGHTEN THE END CAP UNTIL FULLY TIGHTENED SO THAT END CAP IS FLUSH WITH THE HOUSING. USE A 1/8” HEX-KEY IF NECESSARY. IT IS NOT NECESSARY TO EXCESSIVELY TIGHTEN THE END CAP AT THIS STAGE.
INSTALL THE BUFFERING RECOIL SPRING GUIDE ROD AND RECOIL SPRING INTO SLIDE AND ASSEMBLE SLIDE ONTO THE FRAME AND INSERT SLIDE STOP.
USER BUFFERING SPRING TEST – IMPORTANT, USER MUST BE ABLE TO COMPLETE A FULL SLIDE RACK AGAINST THE RESISTANCE OF THE BUFFERING SPRING. RACK THE SLIDE WITH AUTHORITY. IF USER IS CAPABLE OF ACCOMPLISHING A COMPLETE SLIDE RACK WITH THE HEAVY BUFFERING SPRING INSTALLED, THE HEAVY BUFFERING SPRING WILL BE OPTIMAL FOR THE USER. DON’T EXPECT TO HEAR THE “CLICK”, OR “COLLISION” OF THE SLIDE AND FRAME IN THE SAME PRONOUNCED WAY IT WAS HEARD IN STEP 2. THE BUFFERING SPRING EXERTS MAXIMUM RESISTANCE AT THIS “COLLISION” POINT OF THE SLIDE’S REARWARD TRAVEL. HOWEVER, A LESS PRONOUNCED AUDIBLE “CLICK” AT THE SLIDE’S MOST REARWARD TRAVEL MUST BE ABLE TO BE HEARD, OR “FELT”, INDICATING USER CAN RELIABLY ACCOMPLISH A COMPLETE SLIDE RACK.
IF THE HEAVY BUFFERING SPRING IS TOO MUCH RESISTANCE FOR THE USER, DISASSEMBLE THE FIREARM, REMOVE THE BUFFERING RECOIL SPRING GUIDE ROD AND REPLACE THE HEAVY BUFFERING SPRING WITH THE MEDIUM BUFFERING SPRING AND REPEAT THE “CLICK” TEST. IF THE MEDIUM BUFFERING SPRING IS TOO MUCH RESISTANCE FOR THE USER, REPEAT THE DISASSEMBLY…INSTALLING THE LIGHT BUFFERING SPRING AND REPEAT THE CLICK TEST.

IMPORTANT NOTE: THE INCLUSION OF 3 STRENGTHS OF BUFFERING SPRINGS SOLVES THE DOWNSIDE OF OTHER BUFFERING RECOIL SPRING GUIDE RODS CURRENTLY MADE FOR OTHER HANDGUN MODELS – IN THAT, INEVITABLY SOME USERS OF SOME SIMILAR PRODUCTS ARE UNABLE TO BENEFIT FROM RECOIL BUFFERING TECHNOLOGY WHEN HE/SHE IS UNABLE TO COMPLETE A FULL SLIDE RACK VS. THE RESISTANCE OF THE BUFFERING SPRING. INCLUSION OF 3 STRENGTHS OF BUFFERING SPRINGS ALLOWS VIRTUALLY ANY USER WHO CAN ACCOMPLISH A FULL SLIDE RACK WITH A HI-POWER PISTOL WITH THE TRADITIONAL RECOIL SPRING GUIDE ROD, BY AT LEAST USING THE LIGHT BUFFERING SPRING. AND EVEN THE RECOIL BUFFERING EFFECT OF THE LIGHT BUFFERING SPRING IS 100% MORE BUFFERING EFFECT THAT ZERO-BUFFERING EFFECT FROM A TRADITIONAL RECOIL SPRING GUIDE ROD. ***See Supplement “History of the Buffering Recoil Spring Guide Rod”

IMPORTANT NOTE: USE OF A BUFFERING SPRING THAT IS TOO MUCH RESISTANCE FOR THE USERS’ HAND/ARM STRENGTH TO ACCOMPLISH COMPLETE RACKING OF THE SLIDE CAN RESULT IN A “MISFEED” OF THE AMMUNITION WHEN ATTEMTING TO LOAD THE FIREARM.

COMPLETE THE ASSEMBLY OF END CAP

ONCE USER HAS DISCOVERED THE OPTIMAL BUFFERING SPRING FOR HIS/HER USE, IT IS TIME TO COMPLETE THE COMPONENTS’ ASSEMBLY. INSTALL THE OPTIMAL BUFFERING SPRING INTO THE HOUSING, INSTALLING THE “FLAT” / “CLOSED-COIL END” FIRST.

IMPORTANT NOTE: THE THREADS OF THE END CAP REQUIRE ONE OF TWO PREPARATIONS WHEN COMPLETING FINAL ASSEMBLY – USING COMMON “THREAD-LOCK” PRODUCTS / TECHNIQUES.

METHOD 1: (RECOMMENDED) PTFE THREAD SEAL TAPE SIMILAR TO THE PRODUCT PICTURED AND WIDELY AVAILABLE AT STORES LIKE WAL-MART, HOME DEPOT, AND ONLINE.

METHOD 2: LOCTITE BLUE 242, ALSO AVAILABLE AT WAL-MART AND HARDWARE STORES

ADVANTAGES/DISADVANTAGES OF THE TWO METHODS:

METHOD 1: PTFE THREAD SEAL TAPE

DISADVANTAGES: PTFE THREAD SEAL TAPE IS SLIGHTLY MORE DIFFICULT TO WORK WITH, AND IF USER DOES NOT WRAP THE THREADS TIGHT, AND WITH ENOUGH LAYERS OF THREAD TAPE, THE END CAP MAY UNSCREW ITSELF DURING USE. SUFFICIENT LAYERS OF THREAD TAPE WILL REQUIRE USER TO USE A 1/8” HEX-KEY AND SOME AUTHORITY WHEN INSTALLING THE END CAP. IT IS VERY IMPORTANT TO USE ENOUGH THREAD TAPE SO THAT THE RESULTING THREAD RELATIONSHIP CREATED IS VERY FIRM/TIGHT WHEN TIGHTENING THE END CAP. USE 5” ANGLE-NOSE PLIERS OR SIMILAR TO HOLD THE HOUSING FIRMLY WHEN INSTALLING THE END CAP

ADVANTAGES: MAKES DISASSEMBLY EASIER WHEN CHANGING BUFFERING SPRINGS, EASIER TO REMOVE FROM THE END CAP THREADS PRIOR TO REASSEMBLY

METHOD 2: LOCTITE BLUE 242

DISADVANTAGES: MORE DIFFICULT DISASSEMBLY EVEN THOUGH LOCTITE BLUE 242 IS DESIGNED TO BE REMOVABLE WITH TOOLS, IT WILL BE NECESSARY TO CREATE A VERY FIRM HOLD OF THE HOUSING WHEN USING A 1/8” HEX-KEY TO REMOVE THE END CAP. LOCKING THE HOUSING FIRMLY IN A VICE MAY BE NECESSARY. THREADS MUST BE ABSOLUTELY FREE OF OIL OR LUBRICANTS AT TIME OF INSTALL.

ADVANTAGES: ONE DROP OF LOCTITE BLUE 242 WILL CREATE A POSITIVE SEAL OF THE END CAP THREADS TO THE THREADS INSIDE THE HOUSING, SO LONG AS THE THREADS OF THE END CAP AND THE THREADS INSIDE THE HOUSING ARE FREE OF ANY OIL OR LUBRICANTS AT TIME OF INSTALL.

IMPORTANT NOTE: AFTER COMPLETING THE ASSEMBLY, IF USING METHOD 2 (LOCTITE BLUE 242 METHOD) ALLOW 24 HOURS FOR FULL CURING OF THE LOCTITE.

PRIOR TO USE OF THE BUFFERING RECOIL SPRING GUIDE ROD USING EITHER METHOD, INSTALL AND RACK THE SLIDE A MINIMUM OF 50 TIMES WITH NO MAGAZINE INSTALLED, REMOVE THE BUFFERING RECOIL SPRING GUIDE ROD AND CHECK THE TIGHTNESS OF THE END CAP. ALSO, AT THIS TIME, CHECK AND CONFIRM THE TIGHTNESS OF THE “PLUNGER” WHERE IT SCREWS INTO THE “BACK”. THIS CAN BE ACCOMPLISHED WITH TWO PAIRS OF ANGLE NOSE PLIERS BY ATTEMPTING TO TURN THE PLUNGER CLOCKWISE. WHEN THIS CHECK IS PERFORMED, THERE SHOULD BE NO CLOCKWISE MOVEMENT OF THE END CAP OR THE “PLUNGER” RELATIONSHIP WITH THE “BACK”

LUBRICATION:

THERE ARE TWO LUBRICATION POINTS IN THE BUFFERING RECOIL SPRING GUIDE ROD ASSEMBLY. USE A “LIGHT” OR “VERY LIGHT” OIL ONLY AND USE ONLY ONE DROP IN EACH LOCATION AND PREFERABLY FROM A NEEDLE APPLICATOR AS SHOWN. ALLOW ONE DROP TO RUN DOWN BETWEEN THE HOUSING AND THE PLUNGER TO LUBRICATE THE HOUSING/PLUNGER RELATIONSHIP AND AS A PRESERVATIVE FOR THE BUFFERING SPRING, AS SHOWN IN PICTURE #1. NEXT, SLIGHTLY DEPRESS THE BALL LOCATED IN THE BACK WITH A HEX-KEY, SMALL SCREWDRIVER, OR OTHER TOOL AND ALLOW ONE DROP OF OIL TO ENTER THE BACK AROUND THE BALL AS SHOWN IN PICTURE #2. ONE DROP OF LIGHT OR VERY LIGHT OIL BETWEEN THE HOUSING AND PLUNGER CAN BE APPLIED EACH TIME FIREARM IS CLEANED/LUBRICATED. ADDITIONAL OIL APPLIED TO THE BALL, AS SHOWN IN PICTURE #2, IS ONLY NECESSARY IF DEVICE BECOMES WET BY WATER.

TEST OF BUFFERING RECOIL SPRING GUIDE RODS’ CONTROL OF THE SLIDE STOP

INSTALL BUFFERING RECOIL SPRING GUIDE ROD IN HI-POWER, ASSEMBLE SLIDE ASSEMBLY TO FRAME WITH SLIDE STOP. WITH NO MAGAZINE IN THE HI-POWER, PRESS UPWARD ON THE SLIDE STOP AS SHOWN IN ILLUSTATION #1.
RELEASE SLIDE STOP AND OBSERVE THE SLIDE STOP MOVE DOWNWARD SLIGHTLY AS SHOWN IN ILLUSTRAION #2.
INSTALL A MAGAZINE AND RACK THE SLIDE AND OBSERVE SLIDE STOPS’ MOVEMENT UPWARD TO LOCK THE SLIDE STOP IN THE UP POSITION, LOCKING THE SLIDE IN THE REARWARD POSITION AS SHOWN IN ILLUSTRATION #3

FIRST TIME TEST FIRING / SHOOTING W/ BUFFERING RECOIL SPRING GUIDE ROD

WITH STANDARD (OEM) RECOIL SPRING GUIDE ROD INSTALLED, NOT THE BUFFERING RECOIL SPRING GUIDE ROD, SHOOT 13-15 ROUNDS – IDEALLY OBSERVING AND MEASURING THE DISTANCE OF EJECTING EMPTY SHELL CASINGS. THE OPTIMAL DISTANCE OF EJECTING EMPTY SHELL CASINGS IN THE HI-POWER IS GENERALLY 4-9 FEET FROM THE POSITION OF THE HI-POWER WHEN FIRING. THE BUFFERING RECOIL SPRING GUIDE ROD IS NOT A COMPENSATOR FOR AN INAPPROPRIATE RECOIL SPRING OR A RECOIL SPRING THAT HAS SURPASSED ITS’ USEFUL LIFE DUE TO AGE OR USE. SHOOTING A MAGAZINE OF AMMUNITION WITHOUT THE BUFFERING RECOIL SPRING GUIDE ROD ALSO ESTABLISHES THE EFFECT OF NON-BUFFERED RECOIL IN THE SHOOTERS’ HANDS AND ARMS.
DISASSEMBLE HI-POWER AND INSTALL THE BUFFERING RECOIL SPRING GUIDE ROD AND ENJOY. IF POSSIBLE, VIDEOTAPE YOUR SHOOTING AND COMPARE THE “MUZZLE JUMP / MUZZLE FLIP” USING A NON-BUFFERING GUIDE ROD COMPARED TO THE BUFFERING GUIDE ROD.
AFTER TWO MAGAZINES, REMOVE THE BUFFERING RECOIL SPRING GUIDE ROD AND CHECK FOR TIGHTNESS THE SECURENESS OF THE END CAP AND THE PLUNGER RELATIONSHIP TO THE BACK.

WHEN INSTALLING ANY NEW COMPONENTS IN YOUR FIREARM, COMPLETE TESTING OF FUNCTIONALITY MUST BE CONDUCTED ON EACH INDIVIDUAL WEAPON BEFORE RELYING ON IT FOR SELF-PROTECTION. EVERY FIREARM IS DIFFERENT. IF ANY FUNCTION DOES NOT APPEAR NORMAL, CONSULT YOUR GUNSMITH OR CALL BHSpringSolutions LLC at 1-877-423-BHSS.

REPLACEMENT OF THE BALL SPRING PROCEDURE

THE BALL SPRING IN THE BUFFERING RECOIL SPRING GUIDE ROD CAN BE REPLACED. REPLACEMENT OF THE BALL SPRING IS NOT FREQUENT MAINTENANCE WITH THE BUFFERING RECOIL SPRING GUIDE ROD ASSEMBLY. IF, AT ANY TIME IN THE FUTURE, THE BUFFERING RECOIL SPRING GUIDE ROD FAILS THE “TEST OF BUFFERING RECOIL SPRING GUIDE RODS’ CONTROL OF THE SLIDE STOP” AS DESCRIBED IN THESE USE GUIDELINES AND INSTRUCTIONS, THE BALL SPRING MAY BE PAST ITS’ USEFUL LIFE AND IS REPLACEABLE.

THE PLUNGER WAS INSTALLED IN THE BACK OF THE ASSEMBLY USING ONE DROP OF RED LOCTITE 569. TO DISASSEMBLE, HEAT THE ASSEMBLY IN THE OVEN AT 275 DEGREES FAHRENHEIT FOR 1-2 HOURS. USING 2 5” ANGLE NOSE PLIERS OR COMPARABLE TOOLS, THE PLUNGER CAN THEN BE UNSCREWED FROM THE BACK. PRIOR TO REPLACING BALL SPRING, THE PLUNGER THREADS AND THREADS INSIDE THE BACK MUST BE CLEANED OF ALL LEFT-BEHIND LOCTITE AND OIL – CLEAN THOROUGHLY! INSTALL NEW BALL SPRING WITH THE CLOSED COIL (FLAT) END OF THE SPRING FIRST. ADD ONE DROP OF LOCTITE 569 TO PLUNGER THREADS AND INSTALL. DO NOT APPLY ANY OIL TO THE LUBRICATION POINT AROUND THE BALL UNTIL LOCTITE HAS FULLY CURED.

ANSWERS TO SOME FREQUENTLY ASKED QUESTIONS:

Q: Is the New Buffering Recoil Spring Guide Rod Assembly compatible with FN/Browning .40S&W Hi-Powers?

A: Absolutely! The buffering action is exactly the same and will be appreciated by owners of .40S&W HP!

Q: I have a .357Sig Barrel for my Browning .40S&W Hi-Power. Will the New Buffering Recoil Spring Guide Rod help with the excessive muzzle jump that I experience?

A: YES! This scenario is probably the most needy for the New Buffering Recoil Spring Guide Rod for Hi-Power!

Q: Could the Buffering Recoil Spring Guide Rod cause excessive forward slide velocity?

A: No. From the point of full recoil, the Buffering Recoil Spring Guide Rod is going to contribute to forward slide velocity for only about the first 3/8” of forward slide travel, (which will produce more positive “stripping” of the next round from the magazine without increasing the strength of your recoil spring) and after that first 3/8” of forward slide travel, there is no difference in the influence that returns your slide to the forward battery position.

Q: Are there any known compatibility issues in ANY Hi-Power pistols from any manufacturers?

A: Only one. The Hi-Powers made years ago in Canada by Ingliss and the identical Ishapore 1A still made today in India at Rifle Factory Ishapore – these Hi-Powers will also require replacement of the Slide Stop (e.g. BHSS/RDIH Extended Slide Stop for HP). All other Hi-Powers made in Belgium, Hungary, Isreal, Bulgaria, U.S., Germany, Turkey, just replace the OEM Recoil Spring Guide Rod with the New BHSS Buffering Recoil Spring Guide Rod and enjoy shooting with less recoil and muzzle jump!

Q: I understand that replacement of springs is normal periodic maintenance, is there a Warranty on the “hard parts” of the New Buffering Recoil Spring Guide Rod Assembly for Hi-Power?

A: Yes. Hard Parts of the Buffering Recoil Spring Guide Rod Assembly for Hi-Power are covered by a Lifetime Warranty from BOTH BHSpringSolutions LLC and EFK Fire Dragon.

Q: Do I need to choose a different recoil spring when I use the Buffering Recoil Spring Guide Rod?

A: No – if you are using the most optimal recoil spring already, there is no need to change your recoil spring.

Q: Is there a Cure for Hi-Power Addiction?

A: Doubtful. And BHSpringSolutions LLC is exactly the wrong place to find this! 😊

SUPPLEMENT: HISTORY OF THE BUFFERING RECOIL SPRING

Technical Aspects of Multiple Buffering Recoil Springs

The BHSpringSolutions LLC Buffering Recoil Spring Guide Rod for Hi-Power was designed in its’ original form by the founder of EFK Fire Dragon. At the beginning of the 21^st Century, EFK Fire Dragon discontinued the product as the Hi-Power pistol design had been falling out of popularity during the previous decade. EFK Fire Dragon’s original design also had limitations – it was not compatible with all Hi-Powers made by all manufacturers of the Hi-Power and all Hi-Power Slide Stops.

In 2018, while discussing with EFK Fire Dragon a Next Generation Hi-Power Barrel, the EFK Fire Dragon CEO mentioned their discontinued product known as the EFK Fire Dragon “Dual-Action Buffer Spring System”…….and EFK Fire Dragon provided to BHSpringSolutions LLC a prototype of their previous product.

Upon inspection and testing of EFK Fire Dragons’ “Dual-Action Buffer Spring System for Hi-Power”, the BHSpringSolutions LLC founders found that the design had merit, in that it DID decisively “Buffer” the Hi-Powers’ recoil impulse created by the slide/frame collision that happens during full recoil when the slide cycles during shooting. BHSpringSolutions LLC also realized the limitations that the original design imposed – both in terms of compatibility with all Hi-Power models produced to date, and in terms of users with varying hand/arm strength.

One challenge of the EFK Fire Dragon “Dual-Action Buffer Spring System” was the devices’ ability, or inability, to control all Hi-Power slide stops – the EFK Fire Dragon “Ball Spring” was an under-powered component that was not sufficient to control Slide Stops of all the different manufacturers’ slide stops. So, BHSpringSolutions LLC redesigned the dimensions of the some of the parts of the assembly to allow sufficient room for a Ball Spring that could do the job it needs to do.

The second challenge was EFK Fire Dragons’ design of the Buffering Spring. EFK Fire Dragons’ Original Buffer Spring is now BHSpringSolutions HEAVY Buffering Spring. The disadvantages of EFK Fire Dragon’s Original Buffer Spring: Some users cannot complete a full slide rack, AND…the springs dimensions cause the spring to “bottom-out” during slide recoil. In other words, at the slides’ full recoil, the Buffer Spring is “smashed” into a space that is mathematically insufficient for the compressed spring. This “dynamic” has both advantages and disadvantages. It’s good because the Heavy Buffering Spring provides maximum recoil control by using the springs’ running-out-of-space as a “secondary collision” of the slide/frame collision. During BHSpringSolutions’ testing and evaluation, this dynamic never caused a malfunction or a failure of any kind – and at the same time, this dynamic is just brutal on the Heavy Buffer Springs’ longevity.

So….the trade off is: Avid Users of the Heavy Buffering Spring may find themselves replacing their Buffer Spring frequently. And this is not an unreasonable “trade-off”….sometimes absolute Optimal requires more frequent “changing of the oil” (maintenance) – in this case, installation of a replacement Heavy Buffering Spring.

BHSpringSolutions LLC designed 2 additional Buffer Springs: “Medium” and “Light”. Both the Medium and Light Springs are based on geometry that does compute – and as a result, users of the Buffering Recoil Spring Guide Rod Assembly that utilize the Medium or Light Buffer Spring can expect longer life from the Buffering Spring. The “Medium” Buffering Spring is only 0.04mm smaller diameter spring wire and offers approximately 90% of the slide/frame collision buffering effect of the Heavy Buffering Spring. BHSpringSolutions Light Buffer Spring is 0.09mm smaller diameter than the Medium Buffer Spring and provides significantly less resistance to the slide…making the Light Buffer Spring an excellent choice for users with more modest hand/arm strength, while still providing approximately 75-80% of the buffering effect of the Heavy Buffering Spring.

RECOMMENDATION FOR FREQUENCY OF BUFFERING SPRING REPLACEMENT

Heavy Buffering Spring Users – BHSpringSolutions LLC recommends as a “best practices approach” that users of the HEAVY BUFFERING SPRING replace the Heavy Buffering Spring every 500 – 750 rounds.

Medium & Light Buffering Spring Users – Because the Medium & Light Buffering Springs are completely compatible with their assigned job and the space allotted to do their job, less frequent replacement (than with the Heavy Buffering Spring) is appropriate. BHSpringSolutions LLC recommends as a “best practices approach” that users of the Medium & Light Buffering Springs replace their Buffering Spring every 2,500 rounds.

NOTE: Because the BHSpringSolutions LLC Buffering Springs in the Buffering Recoil Spring Guide rod are not “hard compressed” upon install, BHSpringSolutions LLC recommendations for replacement intervals are based on round count only and not impacted by length of time installed.
