Recoil Spring for 3rd Gen 17, 19, 22, 23, 31, 32, 34, 35, 37 & 38 Glock Pistols - these are factory weight recoil springs plated to resist corrosion, even salt water corrosion.
Heavy Composite Plating To Maximize Salt Water Corrosion Resistance. Made From an Enhanced Tensile Music Wire. Optimized Spring Geometry - More Active Coils For Improved Reliability
Extensive Post Wind Processing
White Sound Defense recoil springs for 3rd generation Glock pistols allow the use of aftermarket weighted guide rods without sacrificing the corrosion resistance needed for reliability in military and field environments. These springs are heavily plated with a protective composite that provides a high level of protection, even in the presence of salt water. It is this composite that gives the springs their spotted green and silver surface. When combined with reasonable firearm maintenance these springs will endure the most hostile of environmental conditions.
As these springs are intended for military / tactical applications they are OEM equivalent rate (poundage) for use with standard commercial or military loads.
WSD recoil springs for Glock pistols are made from an enhanced tensile strength music wire designed and produced specifically for this spring. This steel exhibits extreme toughness and durability while providing an excellent substrate for the protective plating. It is the most durable and longest lasting material available for this application. Stainless is not used in the Glock recoil spring application because of the extreme tensile strength requirement imposed by the geometry of the firearm.
Unlike other recoil springs for Glock pistols these springs have open rather than closed ends. This means all the coils are active which improves the function and longevity of the spring. However, the open ends are not effectively retained by most captured guide rods, so the use of uncaptured rods is recommended. Does not work with Gen 4 pistols.
Recoil Spring for S&W M&P Pistols - same benefits and reliability as the Glock recoil spring above but for your full sized S&W M&P 9mm, .40, or .357 Sig.
