Spingco 1911 & 2011 Extreme Duty Semi-Auto Pistol Recoil Springs
WHY CHROME SILICON WIRE? Our pistol recoil springs are manufactured from Chrome Silicon wire.Chromium-silicon alloy is noted for its hardness and superior performance at extremely high stresses. Because of its heat resistance and hardness, the alloy can be used in valve springs and automatic transmissions at temperatures over 275 degrees Fahrenheit. Chrome-silicon was originally developed for recoil springs in anti-aircraft guns where high resistance to shock loads and long life is needed. The endurance limit of Chrome-silicon either before or after shot peening equals that of carbon steel in the same condition. At a given stress value, it can be used at a temperature 100 degrees Fahrenheit higher than Chromium-vanadium and higher hardness without breaking. This alloy provides excellent service for applications in the 5,000 to 50,000 cycle ranges. Available in a sensible range of popular weights, professional shooters and manufacturers who have tested our springs attest to the fact that our springs meet and maintain spec performance better than any other recoil spring on the market today. We perform the Cryogenic Processing of our springs in-house using state of the art equipment.
1911 PERFORMANCE TIP Many of our professional shooters have achieved impressive results by combining our Chrome Silicon Recoil Springs with lighter than "normal" weights when used with our Sprinco Recoil Management Systems. The net result is reduced muzzle dip when the slide returns to battery, hence, improved rapid-fire control! We recommend running a spring weight that is 1 -3 pounds lighter than the recoil spring you currently run with a standard guide rod. For example, for the 5” 1911 shooter who normally fires .45 ACP 230 Gr.Ball ammo, the “Sweet Spot” recoil spring weight is usually a 14# when used with our Recoil Management Systems.
