I purchased the Ruger 10/22 Sporter 22' with stainless steel, and GSG 1911 a few weeks ago. So far things are great with the Ruger 10/22 very accurate I love it. The GSG in the other hand is very inconsistent. It would be dead on for a few shots then horribly inaccurate on some. I noticed after many tarkets that the GSG was keyholing. So i tried different ammo, Mini-Mag, Remington Golden bullet, Winchester SuperX, CCI Velocitor, and it did the same thing. Then I took it apart and everything seemed fine. Until i looked down the barrel with a light. I noticed that there was a peice of metal protruding at the end of the barrel maybe a peice of metal that was not machined all the way? I'm currently at work now, so I'll post up pictures when I get home tomorrow. I was wondering if anyone with a GSG 1911 has had any similar problems or is this just a defect. I emailed ATI with pictures so I'm waiting for them to reply. I'll keep you guys posted.
