I recently purchased 2 BB pistols powered by CO2 cartridges. The first one is a non-blowback Colt Special Combat, a double action version of the Colt 1911. The other is a X-Five made gun, blow back model (moving slide) of the SIG 226.
Both shoot well, at least in my living room. As they are made out of metal other than ordinance grade steel, how long does the metal hold up for, especially the blow back with its moving slide, and other parts? I figure with these being popular in places like Europe, they would see more hard use than the US.
The best experience I have with these types of guns is a plastic and metal version of the Crosman Colt Python revolver in pellet, cheesy gun, but that was 30 years ago. The Walther P-88 that I bought in 2000 and later sold, held up well after heavy use, but the hammer was soft and the firing pin was indenting an ever deeper hole into it. I checked on the SIG that I bought and there is no risk of the hammer having a pin pound on it, just flat surfaces.
