I purchased a Rock Island 1911 ,45 acp match. Upon receiving, I took it apart, inspected, cleaned, lub, installed Hogue wrap around grips and put it all back together. Went to the range today and was extremely impressed with its accuracy. I first test fired 20 rounds, five at a time, at 30 ft. I used a bright orange stick on 6 inch target with 3 inch inner circle bullseye. I used the one inch black square in the center of the target and aimed 6 O'Clock as point of aim. All 20 rounds were in the three inch inner circle. I ended up shooting 100 rounds of Stone Hart Premium 230 gr ammo and had no hangs or jams. The gun worked perfect. I even tried jamming the gun by shooting as fast as I could, but it worked perfect. Even when I shot at 25 yards all rounds were in the 6 inch target (timed fire). If I was still in my prime, I think all would have been in the 3 inch inner bullseye. The gun shoots that good. I took out my Colt Gold Cup National Match could not do any better. Very happy with my new 1911 RI Match.
