So, I bought a new MP9c, came with three mags and night sights, all new from a distributor via the LGS. I shot a full size .40, and compact 9 and .40 as well. My intention was possibly for a smaller off-duty gun and more importantly to get some trigger time and become familiar with the MP due to a transition in the near future to MP's as duty pistols for my agency. Pistol arrives, I shoot and qualify with it and put about 400 rounds through it. I had some accuracy issues around the 20-25 yard lines, we have to shoot from the 25 yard line during one of several qual courses. I chalked it up to a new gun and new trigger that I was not used to. The slide stop release was super hard to use even when staging and I had to sling shot it on reloads. I spent some time at home trying to break in the slide release and my thumbs have had it. I then sent the frame off for a stipple job. Have the gun back and put another approx. 400 rounds through it. The slide stop is still very hard to release, will release with two thumbs on loaded mags or empty mags on the left side, right side for ambi use is not possible unless the gun is empty and no mag in it. I thought this would wear in after use, but I've never had one that was this hard/stiff, I had no issues with any Glock, HK, 1911, or 3rd. Gen S&W pistols as far as the slide release goes. The slide appears to be machined the same as a coworkers more broken in MP9c and the slide stops look to be about the same in the frame as well. But more importantly after reading all the issues with FS MP9 accuracy, I'm thinking this gun has an accuracy issue as well. I'm still getting very inconsistent groups out on the 25 yard line all the way into the 15 yard line. I have not put it in a rest, but after shooting it, I shot the same course of fire with my duty pistol and off-duty Glock and had no issues with 25 yard line accuracy. Maybe its me and the MP trigger, the trigger is different, but I don't think it is that different. So, does anyone know of any SW MP9c accuracy issues other than just on the full size? Thanks in advance, my search fu was weak today. Stay Low
