I use a full size ruger American. Have been very happy with it. Pulled the blade from the trigger, made sure the fore end floated, carved the mag release lever to be flush. It’ll keep a bundle of 40 grain maxi mags under a quarter at 75 yards. After a few thousand rounds it finally got grimy enough that it left an empty case in the chamber. that’s been it’s only bobble. Has killed four coyotes and a truck bed worth of jack rabbits. It’s one of my very favorites. Wait....what was the question? Ha
