M&P 9C Gritty Trigger

[rlight]

I own a M&P 9C and I think it is great. Except for one thing, to me the trigger feels a little gritty. Has anyone else experienced this? Is there a way to make the trigger smoother? Or is it better to replace it with a better trigger? I would appreciate your input.

If you do a search you will find dozens and dozens of posts about trigger pull on this and other forums. If you want to spend money, you can buy Apex aftermarket parts.

If you have some sandpaper, polishing compound and know how, you can smooth the trigger up yourself.

The hardest part is removing the rear sight, but that may not be necessary depending on your gun.

I start out by polishing the areas of engagement between the trigger bar and the striker block and the sear. I also like to smooth the interface between the right slide stop lever and the trigger bar. Of course if this doesn't meet your satisfaction you can always buy Apex parts or take it to a gunsmith.

Scroll down to the bottom of this page, you will find a bunch of links to threads about gritty triggers (and how to correct that).

On the other hand, you might just get used to it. Seriously. Before you do anything to the trigger, do a lot of dry firing and fire 400-500 rounds through it. Then, see how your accuracy is doing. That's the test. Are you shooting straight? If it's still gritty but you are shooting straight, do you really want to mess with it? To me, I found the grittiness in the M&P triggers isn't bad, just different. They ain't 1911s.

I had a gritty trigger when I first got my M&P40C. I saw a YouTube video that was posted on one of the gun sites. If you were to go to YouTube & put that in a search of videos you'll probably find several of them.

The one I saw showed how to polish the trigger bar where it comes in contact with the sear block, that little silver button. That cured my problem by at least 90%. I used a fine rubbing compound & a pencil eraser to finish it off which was probably unnecessary. The trigger bar is a stamped piece & will have a rough finish. I used my fingernail to drag across the surface & when it was smooth I stopped.

Usage of the M&P by itself will smooth the trigger out somewhat but who wants to wait?

I have a stock trigger that felt gritty at first. I now have over 5000 rounds through it and it feels great. I have thought about the apex kit, but it feels so good now i don't want o change it.

I found that most of the grittiness on my M & Ps traced back to the Striker block. Cleaning out the channel it runs in and polishing the contact surface did wonders.

When I dry-fired my M&P 9c in the LGS last month, the trigger pull felt higher than my Glock 17 Gen3. At the range when firing live rounds, the M&P's pull actually feels lower than my Glock's. I understand that the older M&P's have a worse trigger than the newer ones but I am happy with my new M&P 9c and I don't plan on doing anything to the trigger except pulling it a lot at the range.

I agree. I installed the Apex Ultimate Striker Block kit in my 9c and it made very little difference in grittiness. So I took it back out, smoothed the rough surface of the striker block bore in the slide, reassembled and the grit was gone.

Thanks to all of you for the information. I ran across a video the shows how to fix the 'gritty trigger', so I included the link below:

Thanks again..............

The more you shoot it, including dry-fire, the smoother it will become. Save your money on parts and put it towards ammo! Plus, I don't like swapping parts or DIY gun-smithing on a carry gun. YMMV.
