This tool directly replaces the "L" shaped factory tool and will not scuff the pistol at all as its make of Delrin. This tool allows for easy breakdown of recoil spring assembly. Snaps in place no need to center it like stock allen key type tool can help reduce blood pressure by making teardown simpler. Currently we offer 2 tools for the Kimber 3" bushing-less barrel pistols. A short tool that has a step and directly replaces your factory tool allowing you to break down the recoil spring more efficiently and the long tool allows you to remove the slide stop lever with ease. To us they both have a place with the Kimber Ultra II series the reason we are producing both tools. The long tool allows for an easy breakdown however the spring is under more pressure if you???re looking to clean the recoil springs this Short tool is perfect.
