There's a guy over on a 1911 forum that has one, he's pretty fond of it right now (it's still new, so the fondness hasn't worn off yet). It's on page two of this thread. Granted, it's still pretty new, but it seems to be working well enough. I have zero personal experience with them, I can't even recall seeing one anywhere yet. I have an SR-22 and an M&P Compact .22 that I like, but the SIG wasn't available when I got those two.
