I just got one of these in, and tried a couple of mags of BBs this morning, It is really a little too cool for CO2 but just could not weight, I did not try on paper, but a soda can starting at about 20 feet, and had it bouncing around good, got it out to about 30 feet before stopping. I did learn a little oil for the follower in the magazine makes it much easier to slide back and load the magazine which is a little awkward, I did order some extra magazines so I can load up several and shoot some rapid fire then change and let the CO2 cart warm up a bit before loading and using it again. This thing functions just like a standard .45 cal 1911 including takedown, at least as far as removing slide and barrel. I did lube the rails and barrel a little also before shooting and it functions perfectly. It is certainly not as accurate as a pellet gun, but for close range fun I don't think it can be beat.
