Armscor is "Arms Corporation of the Philippines".
Rock Island Armory and Charles Daly guns are actually made by Armscor.
The guns are computer-manufactured from world-class steel. Armscor also makes ammunition, rifles, shotguns, and other things; and owns gun ranges/sponsors shooting teams. Armscor is affiliated with Fratelli Tanfoglio of Italy. But if you want the more known revolvers, go Colt or S&W etc.
I own 2 Armscor guns (.45 and .38 Sp.), as well as a Colt .45, and really I see no difference. When I want to impress people a bit, I take along the Colt. But it doesn't shoot any better. I must say, however, that I shoot about once a month. And I am not a Law enforcement Officer. My firearms needs are civilian: fun and self/home defense.
I think it is true, however, that a Colt will have a better resale value. Still, I don't intend to sell any of the guns so that's not important to me.
