I decided and bought the SR22 Pistol back in late January for cheap shooting. After approximately 400 rounds the gun was jamming quite a bit. When I removed the slide the barrel was extremely loose. I had to buy a new set of hex wrenches to finally get the correct one to tighten it back up. The manual listed the hex wrench with the incorrect size. Went to the range yesterday and barrel is loose again. Upon inspection of the barrel the slot for the location pin has damaged the barrel from flopping around and now the barrel wont seat properly. Im calling Ruger tomorrow!
