Well I made a discovery of sorts today. The magazine spring from a S&W M&P 45 was a direct drop in for the RAP 45 magazine. The S&W spring has 10 coils in it vs 8 for the RAP. Took her out and shot 50 flawless rounds through it. I'm now looking for M&P mag springs.
I began having problems with all three magazines around the same time. They would either stovepipe the round or fail to lock back on last round. I also stretched the springs and now they would function and hold the slide back on last round. Load them back up for 24 hours and the trouble starts...
I've had a 45 M&P for a year now. I have to say it's quite a gun. I decided to purchase a new duty weapon and got the M&P. The trigger pull was horrible coming in around ten pounds. Mine shot low and to the left for the first 500 rounds. It did shoot tight groups though.
I've read that 500...
