I'm looking for some advice on a backyard plinking pistol. I have been tempted by the 1377, HW45/75 and the Gamo Compact, but after some serious thought, I want something that is fun and and can be used in a rapid fire way, I think I have to opt for co2. I also think I'll probably be better off staying away from a gun that fires BBs, my yard is all concrete and I really don't want ricochets, if for some reason there is an errant shot.
At the moment I'm looking at the S&W 586, the Colt Government 1911 A1, and the Gamo PT-85. Are there other pistols I should be looking at? Pistols with a silencer/moderator available would be a plus.
