Trying to shoot a STI Trojan with a Kimber .22 conversion, seems to be a very picky eater. Only works well with some high velocity ammo and 99% of the time with hyper velocity. On some FTF's the action was cycled but not far enough to #### hammer, thought hammer spring may be too heavy but then on some FTF's seems firing pin did not strike hard enough.
Pistol works fine with .45
