A great upgrade for your pistol Main rod is machined from one solid piece. No threads to cause stress points where this part can break. The tool-less design is brilliant. The lock lever is slightly below flush and designed so it stays put until you wish to lock it in place to disassemble your pistol, with no tools! That's right. No tools, pins, or clips needed. It locks the spring, guiderod, and spring plug in one neat assembly so you can easily remove it or replace it. There are two rods available. One fits 1911, Kimber, STI and SV with 5 inch bull barrels and the other fits standard 1911/2011, Kimber, Para, and other bushing barrel type guns. Pistol must be able to remove spring plug from the rear of the slide. Includes Tool-less Guide Rod with Full Shoulder Reverse or Standard Bushing Barrel Type Spring Plug. Note: these do not work with the Springfield Operator TRP series guns. The bushing model rod is $60 and the bull barrel model rod is $70.
