I have a Mark III Hunter with a Majestic Arms quick strip kit, Majestic three lb trigger, Majestic slide racker assist, Volquartsen muzzle brake, and a Bushnell Trophy red dot that I use in steel Challenge matches. Wherever the dot is, a bullet hole will appear.
ruger m 1 target 22/45 is a super gun. accurate and fun to shoot and have had it for a very long time and not a single problem with it or the factory mags that came with it.
I have a 22/45 target with that I added the tandemkross sling shot mod and a mk II bushing, it's crazy accurate and will eat any ammo I have stuck down it. I have some volquartsen parts I want to add to it down the road.
