1911 Main Spring
The M1911 pistol, like all pistols, relies on several springs for proper function. Arguably the most significant spring, however, is the main spring, which is a fitting title considering the importance of the task it is designed to complete. Essentially, the 1911 main spring is a hammer spring, holding the hammer under tension prior to a trigger pull. In other words, no main spring equals no hammer movement and no discharge.
In any pistol that utilizes a hammer as opposed to a striker, the hammer is one of the most vital components. Aptly named due to its similarity in both looks and functionality to the common tool, the hammer is responsible for striking the firing pin, which in turn strikes the cartridge primer and completes the firing sequence. The hammer is only able to perform this function because it is held under spring tension by the main spring.
As noted, the 1911 main spring is akin to a hammer spring. It is the spring that keeps the hammer under tension and forces the hammer forward after a trigger pull. In the 1911, the main spring is located inside the main spring housing at the rear of the frame. The main spring housing also houses the main spring cap and the main spring pin retainer. This newly manufactured part was manufactured to mil-spec 1911 specifications and features a black oxide finish. Note that a wide variety of the 1911 mains springs exists. Ours is designed specifically for mil-spec pistols.
Spare parts are an important consideration when it comes to firearms. Like any machine, firearms rely on a series of parts to function properly, especially all components that impact the firing sequence. In general, if a part breaks or fails, a repair or replacement becomes necessary immediately – not only to keep a firearm functioning properly but also to ensure the safety of yourself and those around you.
It is also important to consider availability. At this time, Keepshooting.com is seeking to provide our customers with a wide selection of replacement parts for the M1911 pistol.

Repeated compression and decompression will weaken any spring and eventually lead to breakage. Basically, the more rounds put through your firearm, the greater the chance a spring will break.
