The Kimber stainless recoil spring plug (brand part no. 1000301A) is the direct-fit cap for the front of the recoil spring assembly on a Kimber 5-inch 1911 that runs Kimber’s full-length guide rod. The plug holds the spring seated at the muzzle end of the assembly, so tension stays where it belongs through every cycle of the slide. It is sized for the full-length rod system, which means it will not work on a 1911 built around a standard GI-length guide rod. That specificity makes it the right part for a recoil spring rebuild or for replacing a worn or damaged factory plug. It is a small stainless part that keeps a Kimber 1911 running the way it left the factory.
