I shot it today and didn't have any problems using the factory mag. It shot to point of aim at 10 yards as long as I did my part. I'm very happy with the Kygunco service and the price was great. Needless to say, I'm very happy with the Rock Island Armory 1911. 3/28/2025 ** ** ** ** ** ** Chris Lebanon, KY This is my first 1911 and .45 and I love this gun. Has a good kick, smooth trigger. Would have been nice e to have to magazines and bigger capacity, but other than that for the price I have zero complaints. I love going to Ky gun. People there are awesome 3/12/2025 ** ** ** ** ** ** Mike San Antonio, TEXAS This firearm is top quality. I own several other 1911s and have owned more than 20 over the last 15 years. Some were good, some were so-so. Few were a gun I carry everyday. This RIA is. Im very pleased with the performance and kygunco. Nice job. 3/21/2014 ** ** ** ** ** ** Drew CLT, NC I bought this just before Christmas and was more than happy with the gun, price shipping time. This is the tactical model with the ambidextrous thumb safety, commander style hammer, Novak style sights, skeletonized trigger and beaver tail grip safety. The pistol has a full length guide rod and has proved to be a great shooter. I havent had a FTF or FTE in 400rds. 2/24/2014 ** ** ** ** ** ** Stephen San Antonio, TX didnt buy one here, but this gun fits the bill. 3/31/2013 ** ** ** ** ** ## Don't Forget Your Ammo ```json
