There’s always a better gun.
I used to carry a CZ82 daily, but my age has caught up with my proficiency. I find my ability to hit a milk jig of water at twenty and thirty feet is all about practice, and with my 22 magnum revolver I can make those hits consistently and accurately with follow up shot(s). I carry it and a speed loader, with Hornady HP with the red pills removed. The milk jugs explode with the first hit, and I figure that should slow an attacker enough for me to get the second round in the melon.
