Hello all! New guy here. I have some other pistols but the ammo cost is prohibitive to shoot any decent volumes, so I got myself a Mark III 22/45, bull barrel, SS, 5.5". I went to the range last night and put about 200 rounds of Thunderbolt through it. I had 3 FTF's, and 1 jam (operator error). I was very pleased with the performance of the gun. Frankly, shooting .22 is just about as much fun as the bigger stuff and WAY cheaper. I did manage to do strip it, clean it, and get it back together!! Of course I had the manual at hand. Anyway, I'm very pleased with the pistol and I hope to learn some good Ruger stuff here. Thank you.
