Colt Commander .177 Caliber Steel BB Air Gun Pistol THIS IS THE ONE YOU WANT!!!
I don't know how to truly relay my love of this air pistol. It's my first blowback and I fear I've set the bar so high nothing else will compare. I had an issue .45 while serving as an MP in the Army and this thing feels and fires so similarly I won't even bother with the differences because they truly are minor. It's ridiculously accurate and easy to shoot. The dropout mag loads rather easily once you figure out how it works and the mag release is so smooth you have to remind yourself it's a BB gun, and not a real mag. The only negative is that it eats CO2 like a hungry pitbull on a porkchop. I get three, maybe four mags down range before I notice the drop in velocity and power. Still, that said they're an awfully fun 4 mags!!!
If you want a solid, all metal (save the grips - which you can change easily enough to something nicer), blow back I triple dog dare you to find something better for the price. Prior to this my S&W revolver was my favorite handgun, but this knocked that so far out of the running I almost feel bad for it, lol.
