They were around a while and disappeared. They are back - not sure if it is the same people or if they just bought the rights to the name.
1 think that distinguished their 1911s but what I don't like - They chop out part of the rear of the slide, and move the rear sight up a bit. But, that takes out 1/2 an inch, or more, of your sight radius.
All I remember about them is the early stainless ones had a bad galling problem. I dont know about the resurrected name or owners.
I too do not like the sights/slide OR the officer length grip on almost all their models.
I had one back in the late 70s, mine worked okay. It was the first of the subcompact 45s. The sight radius was a bit short, but for close range it worked okay. It had a six round mag, but would also work with a standard 1911 mag. I don't have any experience with the newer ones.
