This is the Sig I have. It's gloriously crafted, virtually indistinguishable form the real thing. It's also gloriously unreliable. The amount of gas required to operate the action means I rarely get to the end of a mag before running out, which is a pity as the no-ammo snap back action is great. The all metal framework gets cold damn fast, so I've taken to carrying the mags in my pocket during fights to keep them warm, only loading and racking the slide when I know I'm gonna be doing using the pistol for an extended period. Leaking hasn't been a major problem, although there's been the odd time where I've drawn it, pulled the trigger and nothings happened, which is frankly terrifying, akin to that nightmare where your a child, rock upto high school and realise you forgot to put your clothes on.
