jimmyj, I have handled several different 1911 style handguns from this company. They are a good, solid, well functioning 1911 in three calibers I have tried. 45 ,9mm, and 38 super.
They have most if not all parts that will interchange with all the major brands of G I 1911 style pistols.
As stated above Armscor, is the corporation head of Rock Island Armory, with beginnings in the Philippines in the 1900s.
According to a back issue of American Rifleman, "they have likely produced more mil-spec, 1911 firearms than any other firm, WORLD-WIDE !
Certainly not as well finished and dressed-up as the better known brands, but for the money, a solid shooter, with factory back-up in Nevada, and, I believe, a new plant in Montana.
Rock Island Armory, Philippines, referred to in "1911 jargon" as RIA, and "Rock", has no affiliation with the Rock Island Arsenal of WWII and earlier fame.
I think I heard the "Rock Island" name, is because of the factory location in Philippines area named ROCK ISLAND.
People who REALLY like them actually call them selves "Rockheads".
I would not trade a Colt / S&W / Springfield Armory / maybe not even a Kimber,(smirk) for one straight up, but, I also can not buy those major brands in the 450 dollar category either.
Wish I owned some, but so far good friends have allowed me to shoot theirs, and I may lay one away soon.
