I've got quite a few of these, and enjoy them quite a bit. I have the
SIG Sauer We The People 1911 on my desk right this second. That design is the same as the aforementioned Tagfolio as the same magazines fit it. That is probably my most accurate BB slinger in a pistol, and it feels good, and is fun to shoot. It only gets about 2 1/2 mags per Powerlette. I have two of the
SIG Sauer M17 along with a bunch of extra magazines and a couple extra clips. This one is really fun to shoot, pretty accurate, and both this and the 1911 break down really easily. Finally, one that I always pull out when friends come over because it is a "blast" is the
Beretta 92A1 full-auto BB slinger. That one isn't accurate at all, and actually has a "hop up" like a air-soft pistol, and I think that this makes it worse. All this said, I put a laser sight on it to help with this issue, and only shoot it at about 25 feet as it isn't much fun farther than that. Finally, it isn't a pistol, but I have
the Crosman DPMS that also has a "happy switch" to go full auto and has blow-back action. This one is a lot more accurate. I've got a number more that are revolvers, and non-blow-back, but you didn't ask about those.
Anyway, I hope that this helps your decision. Happy shooting!
