M&P9c Trigger A Bit Gritty

[Spartikus]

I recently purchased a M&P9c and LOVE it! In fact, one of the reason I purchased it was because the trigger felt better than any of the Glock, XDM, or similar striker fire guns. I have now put 600 rounds through the gun and have started noticing that I can feel just a little bit of grittiness right before the trigger breaking.

I was curious if anyone has experienced this and if so have you done anything to make it better. I know about dropping in he Apex trigger but I would like to stick with the stock trigger for now and see what I can do.

There is a notch that sticks out on the bottom of the slide that forces the guide (sorry I don't know the technical terms) over to unblock the firing pin safety. I think that grittiness I feel happens when it pass that notch and rubs against it so I thought maybe polishing that notch would improve the feel. Thoughts? Am I making any sense?

I was told the apex USB (ultimate striker block) part will fix this.. but I have yet to do it myself. anyone else install only the USB by itself?

So here's a picture of the bottom side of my slide and I have circled the notch that I am thinking I could somehow buff or smooth out to help the feel of the trigger. Anyone know if this would help?

Don't mess with that!

While you have it apart look up on this site Burwell Trigger job, and do as it indicates and I think you will be much more satisfied with the stock trigger. Or, you can spend some money on the Apex trigger kits. Depending on experience!

Nooo!! Don't start modifying the slide! An Apex USB with make the trigger take up as smooth as silk. Another option would be to follow Dan Burwell's instruction to make your own USB. I prefer to buy the part and drop it in.

The bump you have circled has nothing to do with the trigger pull being gritty, its purpose is to to kick the transfer bar to the right and disengage it from the sear when the slide moves to the rear. Before you taking the gun apart and polishing parts google "The Burwell Trigger" job that AZ155 mentioned. read the PDF file a few times with the field stripped pistol in your hand paying close attention on how all the parts interact.

Thank you all for your input. The reason I asked is because I am new and don't know exactly what should be done and don't want to do the wrong thing. Sounds like the Apex USB is the way to go after doing lots of research. I'm just not excited about removing the rear sight to replace it.

I guess I was lucky, my 9c's trigger is very nice...

Rear site removal is a pice of cake if you have an extra set of hands for a few minutes. I did mine with the wifes help in 15 min(she held the small vice)and the tool Apex sends you help's alot. Just use pencil to mark where your site was.

Well, I broke down and purchased the Apex trigger kit DCEAK for my M&P9c. I'm excited to get it installed and feel the difference. For people reading this, the stock trigger doesn't suck, but I think Apex makes a nice product that will enhance the feel of the trigger and hopefully it will help me be a bit better with my accuracy. Obviously most of that comes down to training and practice as well.

Hey the more you practice with your gun the better you get with it. I still am not completely satisfied with my skills but I will tell you that with more practice and concentration you will become a very good marksman in no time.

My first times at the range in over 20 years were let's say all over the place but now I have a lot of shots going quite close to the intended area especially with any of my nine millimeters, and am getting better and faster with my .40 as well as my my less than three month old full sized 45!

Just like I told my oldest daughter before qualifying for her carry permit she was shooting a bb gun in the back yard for practice. She took her gun to the range and hit the paper 50 out of 50 even shooting from the hip and even embarrassed me with her great shots!

I really have no problem with the stock trigger. It works for me just like it is. I chose the M&P 9c and I still like that choice. It's a great weapon!

I totally agree! I spent an hour at the shooting range trying different guns (just pulling the trigger and feeling the guns) and the M&P by far felt the best both in my hand and pulling the trigger. It also just feels better made than most other guns in that category. I have nothing but praise for it and only hope I learn to shoot it as well as my S&W 1911 E Series!

I figure the Apex trigger is just a way to try something different and lots of people seem to be really happy with them. Also, it should help me a bit with picture upset when the trigger breaks.

I just bought a M&P40 pro series and used Dan Burwell's instructions. I'm no gunsmith, but his instructions are very well done. I'm very pleased with the results. Smooth 3 1\2 lb trigger.

I took the same rout. Nice and slow, once you remove too much, it's too late! So far I am pleased with the results. Nice smooth trigger around 4lbs. I finally got my new M&P 40C to the range and was really impressed. I put exactly 150 rounds down range. I could not be any happier.

The fellow next to me had a M&P9 FS with a full Apex kit down to the trigger as well. Our groups were very similar at 10 yards. I'll wait a little longer before going down the Apex road. So far, I really like my new 40C.

Easy:
Get some leather to pad vice jaws
And a brass punch
And a brass hammer

Use a vice that is bolted to a bench. Loosen the set screw and tap the rear sight to the ejection port side. Rear sight normally comes out easily. The front is a pia.

Thanks for the suggestions. I already have the brass hammer and it came with a drift punch similar to the one you gave me a link to so now I just need to get the leather (great suggestion) and a roll punch.

I purchased a normal 1/8" punch from my local hardware store but it seemed like it would be really tight and was concerned that I could accidentally gouge some of the plastic with the sharp edges of the punch. Any suggestions for a punch and should I got a bit smaller?
