SEVERAL PROBLEMS:\u00a0<\/strong><\/p>\n

    \n
  1. \u00a0\u00a0\u00a0\u00a0\u00a0 All 1911s are not created equal.\u00a0 Nobody seems to know how many firearms manufacturers have built a 1911 semi-auto pistol.\u00a0 And even though springs may be interchangeable between most of them, not all 1911s function best with the same recoil and main spring combinations.<\/li>\n
  2. \u00a0\u00a0\u00a0\u00a0\u00a0 The design of the 1911 is so excellent, and so robust, that many 1911s continue to function, even after all the springs have become weak.\u00a0 This is both a blessing and a curse \u2013 because although the 1911 may seem to function fine with unhealthy springs \u2013 accuracy will suffer and rearward slide velocity will become excessive, causing premature wear of parts.\u00a0 In addition to causing your 1911 to wear out faster, weakened springs make great \u201criding partners\u201d for a host of potential 1911 malfunctions, including:\u00a0 Encountering ammunition with \u201chard primers\u201d (failures-to-fire) goes hand in hand with an unhealthy main spring that no longer causes the hammer to strike the firing pin with sufficient force.\u00a0 Experiences of failures-to-feed go hand in hand with a weakened recoil spring that no longer returns the slide to battery with sufficient authority.<\/li>\n
  3. \u00a0\u00a0\u00a0\u00a0\u00a0 Variations in .45ACP ammunition, exist today, that did not exist in 1911.\u00a0 The varieties of bullet weights and pressures in ammunition today constitute a moving target.<\/li>\n
  4. \u00a0\u00a0\u00a0\u00a0\u00a0 All coil springs in the 1911 are compressed, when installed.\u00a0 They are expending energy (wearing themselves out) just by being installed in a 1911.<\/li>\n<\/ol>\n

    \u00a0<\/strong><\/p>\n

    Solution:\u00a0 The BHSpringSolutions 1911 Optimizing Spring Kit<\/strong><\/p>\n

    \u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0<\/strong>All BHSpringSolutions Optimizing Spring Kits, for the 5\u201d barrel 1911 .45ACP, contain 3 Recoil Springs, 2 Main Springs, Optimal Firing Pin Spring, Plunger Spring, Magazine Latch Spring, and a Firing Pin Block Safety Spring in the Series 80 kits.<\/p>\n

    Why 3 Recoil Springs and 2 Main Springs?\u00a0<\/strong><\/p>\n

    Generally, the distance of ejection of empty shell casings, gives us feedback about function and slide velocity.\u00a0 And generally, we look for this distance to be in the 4\u2019 \u2013 8\u2019 range.\u00a0 This is where \u201cAll 1911s are not created equal\u201d, applies.\u00a0 During our testing with 230 gr standard pressure ammunition, we found distance of empty case ejection to be in the 4\u2019 \u2013 6\u2019 range with our standard 16 lb recoil spring and our Heavy Main Spring.\u00a0 When we changed over to our Light Main Spring, distance of empty shell case ejection was an additional 1\u00bd\u2019 \u2013 2 \u00bd\u2019 further, depending on the ammunition being tested\u2026.giving us empty case ejection in the 6\u2019 \u2013 8\u2019 range.\u00a0\u00a0 With the lighter main spring, we could then go to our heavier 18 lb recoil spring, and tame the recoil a bit, and reduced the empty shell case ejection distance and increased the authority of the slide\u2019s return to battery.\u00a0 Our 18 lb Recoil Spring also nicely controlled +P .45ACP ammunition, particularly with the heavier main spring.\u00a0 These results were in our 1911 used for testing which is a recent production Remington R1.\u00a0 The owner of a Colt GI 1911, made in 1930, may find a slightly different combination to be optimal, and the owner of a Springfield 1911 may find yet a different combination to work best.\u00a0 And also, the right combination of Main Spring and Recoil Spring is not only about the basic science involved in measuring distance of empty shell casings \u2013 there is another factor \u2013 not all shooters are created equal.\u00a0 Our 3 Recoil Springs and 2 Main Springs, standard in all BHSpringSolutions 1911 Spring Kits, also take into account this other important fact: \u201cIt\u2019s also a feel thing\u201d\u2026\u2026in other words, as long as function is reliable and the empty shell casing ejection distance is in the desired range, the right combination of recoil spring and main spring, in a particular 1911, for a particular shooter, also depends on which combination yields the best performance results for the shooter and his 1911.\u00a0 Many 1911s will function reliably with our 16 lb recoil spring and either of our Main Springs, and many 1911s will function well with standard pressure ammunition with our heavier 18 lb recoil spring and lighter Main Spring as a combination \u2013 and the final determination of \u201coptimal\u201d will be based on the combination that \u201cfeels\u201d best, and enables the owner\/shooter to perform best.\u00a0 Ultimately, this optimal combination is found by the 1911 owner and his handgun, together.<\/p>\n

    Many manufacturers go to great efforts to make quality 1911s, with consistency of build quality that, given today\u2019s technology and modern machinery, is better than it\u2019s ever been in history.\u00a0 Unfortunately, many 1911 owners (and manufacturers) are missing the best possible 1911 performance by not finding the best possible combination of Recoil and Main Spring.\u00a0 The importance of these two springs, working together like gears in a well-oiled machine, cannot be overstated with respect to the 1911.<\/p>\n

    What is the difference between a \u201cSeries 70\u201d and a \u201cSeries 80\u201d 1911? \u00a0\u00a0\u00a0\u00a0\u00a0<\/strong><\/p>\n

    The Series 80 is a more modern design, containing a mechanical firing pin block safety, intended to prevent accidental discharge if the 1911 should be dropped on the muzzle with a live round in the chamber, by preventing the firing pin from moving forward except when the trigger is pulled.\u00a0 Series 70 1911s contain no such device and are fully dependent on the strength of the Firing Pin Spring, to retain Firing Pin in it\u2019s rearward position, in the event the 1911 is dropped on the muzzle with a live round chambered.<\/p>\n

    What is the difference between a Series 70 and a Series 80 Spring Kit from BHSpringSolutions LLC?<\/strong><\/p>\n

    Series 80<\/strong>\u00a0Spring Kits from BHSpringSolutions LLC contain a Firing Pin Block Safety Spring, a light Firing Pin Spring, and one each of our Heavy and Light Main Springs.<\/p>\n

    Series 70<\/strong>\u00a0Spring Kits from BHSpringSolutions LLC contain an enhanced (heavier) Firing Pin Spring because, the Firing Pin Spring itself is your only protection against accidental discharge in the event of a muzzle drop in the Series 70 design.<\/p>\n

    More On Main Springs<\/strong><\/p>\n

    Each Series 70 kit contains one Heavy Main Spring, and 2 Light Main Springs.<\/p>\n

    Because of the enhanced resistance created by the Series 70 Firing Pin Spring, shooters who prefer performance associated with the Light Main Spring should note that we suggest replacement of this Light Main Spring twice as often as other springs in the 1911 Series 70.\u00a0\u00a0 BHSpringSolutions recommends a \u201cbest practices\u201d approach to 1911 spring replacement of \u201cEvery 5 Years or 5,000 rounds, whichever comes first\u201d.\u00a0 The one exception is use of the Light Main Spring in combination with the Heavy Firing Pin Spring of the Series 70 \u2013 in which case we recommend replacement of the Light Main Spring at approximately 2 \u00bd years \u2013 this is the reason for two Light Main Springs in our Series 70 1911 Tune-Up and Optimization Spring Kits.<\/p>\n

    Plunger Spring:<\/strong><\/p>\n

    Contained in all BHSpringSolutions LLC 1911 Optimizing Spring Kits.\u00a0 This multi-function spring is located inside the little tube you see on the left side of your 1911.\u00a0 One responsibility of this spring is keeping the manual safety in the \u201con safe\u201d position.\u00a0 And, since \u201ccocked and locked\u201d also known as \u201cCondition 1\u201d, is the most common condition for carry of the 1911, keeping this spring healthy should be a priority for all 1911 owners.\u00a0 A healthy plunger spring reduces the chances of unintended movement of the manual safety from the \u201con safe\u201d position to \u201cfire\u201d position.\u00a0 A correctly made plunger spring has an intentional \u201cdog leg\u201d in the center of the spring because this design works best. \u00a0The Plunger Spring must push in opposite directions, simultaneously, all the time.\u00a0 The \u201ckink\u201d, or dog leg in the center of this spring creates a stationary position in the center of the spring because each half of the spring has it\u2019s own job to do, in opposing directions.\u00a0 A side benefit is that the Plunger Spring doesn\u2019t fly across the room during disassembly when it\u2019s made with the \u201cdog leg\u201d design.<\/p>\n

    Magazine Latch Spring:<\/strong><\/p>\n

    This spring is responsible for positive lock-up and retention of the magazine in the 1911 grip frame. \u00a0If you read many handgun reviews, it probably won\u2019t be long before you read a reviewer who comments that he or she unintentionally manipulated the magazine release during shooting or deholstering.\u00a0 Of course, no magazine latch spring can stop this from happening if a shooters thumb is going places it shouldn\u2019t go at the wrong time\u2026\u2026.but a healthy magazine latch spring does decrease the likelihood of untended manipulation of the magazine release, as much as possible.\u00a0 A healthy magazine latch spring provides maximum resistance on the magazine release, while still allowing smooth manipulation and function when release of the magazine is intended.<\/p>\n
