I've got a similar problem shooting semi autos vs revolvers. I started shooting hand guns about 2 1/2 years ago and shoot my two GP-100s and model 10s much better than either of my semi autos. I've been frustrated to the point of thinking about selling my semis too. I decided to keep my P226 Sig 9mm and get an instructor instead of wasting more ammo trying to diagnose myself. I'm going to concentrate on the revolvers which I enjoy shooting before I tackle the Sig again. Range trips are a lot more fun when you hit what you're aiming at. I'd keep a 1911 if I were you or you may end up on the "guns you have wished you didn't sell" threads. Thanks for posting.
