I just bought a new Ruger MKIII 5.5 inch stainless bull barrel, and had a chance to put about 500 rounds through it this weekend. Let me tell you this thing is a shooter! It did not have a single malfunction of any kind, very accurate and just a whole lot of fun! Here the new toy is MKIII with my other .22 pistol, a Smith & Wesson 617 6 shot pre-lock.
