Found one at the gunshow yesterday. It looks brand new and I got it for $375. No idea what they sold for new, or if they're well thought of or just junk. Haven't shot it yet and have no idea what ammo to use. Just looked like a good plinker at a fair price.

It's a rebranded GSG 1911-22. Marginally ok pot metal gun that can be had for much less. I wouldn't pay over $150-$200 for one but that's just me. It's not in any way shape or form made by Sig. Do an image search for GSG 1911-22 cracked slide. The rear of the slide tends to crack and fall off alone the rear sight cut and down the cocking serrations.

I have a GSG with more than 6K through it, shot it today, no problems. I paid $350 for mine new six years ago.
