I haven't shot the SIG, but I have shot the GSG 1911 which is basically the same pistol, just rebranded. The gun I shot was OK, using CCI Mini Mags. I personally would not buy one because of the zinc alloy construction. I opted for the Browning 1911 .22 A1. A bit more pricey, but it is made of all T6 aircraft grade aluminum and about 85% the size of the full size 1911. BTW - the SIG 1911 .22 is not made by SIG, they license their name on the gun.
