I have the Colt 1911 version - most of these guns are made by Umarex - Colt, Beretta, S&W, and even the Walther Lever Rifle I think. They are quite well made and made to use. I probably have nearly 1,000 rounds through my Colt. It is much more accurate than I can shoot. When I'm practicing regularly I can keep most shots in a 2 inch bull at 7 to 10 yards double action. I can get about 40 shots at full power then it fades until about 60 to 80 shots. Up to now I have mostly used Daisy and Crossman pellets. I use it strictly for paper.
I'm seriously thinking about the S&W as one gun review said they were a little better than the Colt or Beretta versions - and it would be more like my revolvers. But I've blown all my $ on a air rifle and gear lately so gotta save up.
Only problem for my Colt is that it doesn't shoot in single action - and thats a frustration. I sent it to Daisy the authorized service agent and they tried but didn't fix it. So I just shoot it DA but I'm thinking of sending it back again.
GB - I miss the airgun forum too, but I think you are wise to keep focused on firearms. Straight Shooters has a great forum and excellent product reviews on many airguns. There is an American Airguns Forum and Chinese Airgun forum for people interested in those disciplines.
