I had a NiteHawg when they first came out.
The gun ran great, but the finish didn't last long, after 3 months it looked like I had carried it for 10 years in a sand paper lined holster....OK it wasn't that bad, but you know what I mean.
I eventually sold it off, for me the double stack just doesn't do it for me in 1911s.
Oh, spare mags will run you $49.00 a piece from the factory, $55? from Brownells, and don't even bother with the Promag magazines.
