(5 out of 5) a great M1911!!!
by Christian M. from Elkins Park, PA on October 4, 2026

This was actually recommended to me by a YouTuber that often has a Rock Island Armory M1911 when doing various .45 ACP tests, and I decided to buy one of my own. Good thing, too, because this gun not only looks great, but has performed rather flawlessly so far. Would definitely recommend this for those looking for a good 1911, especially if you’re on a budget and don’t want to spend over $1K+ for a Colt!!!
