I owned one a few years back. I even took a local practical pistol class with it.
The grip angle is similar to the 1911, but the grip area is quite a bit blockier than the 1911. The bore axis is higher. The trigger is nowhere near as good as a tuned 1911's, though it is still perfectly adequate. Mags are not easy to find. Mine was totally reliable, unlike many 1911s.
It's a good pistol, and easily worth $350. It fits pretty well in holsters for the SIG P220/P226.
