Perfect... - Volquartsen Firearms Pistol Competition Kit, Ruger MKII/MKIII/22/45

I installed on a bull barreled mk iii. Not only is the trigger pull amazing, but having the magazine drop free is amazing. I already had a red dot on the pistol, so I now have a very easy shooting, very accurate, fun pistol. Installation instructions are lacking, I recommend watching a few YouTube videos, or, better yet, set a small action camera up and record disassembly. Small details like spring orientation is critically important, and if you're not familiar with the platform it can be frustrating.
