Just got a new never fired Remington R1 .45 acp. Using Remington UMC 230 grain ball nose ammo. Out of 120 rounds I got maybe 2 consecutive shot off 4 times. Had it checked out by a Gunsmith, he found not problems other than tight tolerance in the machining. They are tight. Now he told me just to keep putting lead through it. He did say that barrel is not setting in the slide, where the 3 ribs met on top of the slide. The term is I believe "the battery". Just need to know if anyone is having this problem or should I just send the gun back to Remington?
