The Thunder Mountain Custom Recoil springs are manufactued for us by the leading gun spring manufacture in the US.  Manufactured on CNC spring machines using the best Chrome Silicon spring wire availible.

Recoil springs fit over your handgun's guide rod and control how the slide functions. In general, heavy loads need heavy springs and lighter loads need lighter springs. A spring that is too light can cause the handgun to open and close early and hard, increasing the felt recoil and battering the frame. A spring that is too heavy can cause the slide to be hard to open and could even keep the gun from cycling completely, jamming it. Installation requires disassembly and reassembly of the slide.

How often should the recoil spring be changed? The recoil spring should be changed, at the latest, when it has lost 0.500” of free length from new. At this point, the spring has suffered a considerable reduction in load exerted at installed (when the gun is in battery).

How long will an TMC recoil spring last? In independent testing, TMC spring have endured in excess of 100,000 compression cycles. We don’t recommend going that long between changes however. With an TMC spring, practice routine maintenance and change it once a year.

Should I use a spring buffer?
We do not recommend the use of a spring buffer in the 1911 pistol. Buffers tend to be a bandage for a recoil spring that no longer performs adequately. Put a fresh spring in instead. Buffers reduce slide travel which can have an adverse effect of feeding reliability. In addition, buffers can break apart during firing and make the gun inoperable.
