Pro Series disappointment

I remedied the "gritty" trigger with a little emory paper (320 then 400 grit) on this surface. I saw it was a little rough, and as soon as I sanded out the roughness, the gritty sensation went away. I just accelerated the same wear as pulling the trigger a thousand times.

This portion of the bar is what pushes up the safety plunger just before the sear starts moving.

Can't believe that no one has asked this..when was your pistol produced? Check the fired shell casing envelope for the test fired date. My Pro 9mm produced only a few months ago has a very smooth trigger. My 40c produced the end of last year has a very gritty trigger that will need some work. I realize the Pro has some factory trigger work done to it, but S&W also reportedly started using different sears at the beginning of 2013. If your Pro 4.25 was a 2013 production, I would fire around 1000 rounds and if it doesn't go away, send it back to S&W for possible repairs
 
Fixed it mostly

Thank you AwfAxis - that was the ticket. Took the 5" Pro down and sure enough a burr on that area. Sanded away and this reduced it a lot - still some grit feel but 80% better.
 
My 4.25 Pro had a fairly smooth stock trigger. I still switched it out with an Apex FSS kit. This made a nice pistol into an outstanding pistol.
 
dry fire works

Dry fire it/shoot it, should get better directly.

Dry firing is the best way to break trigger in. It will lighten up over time and get less grity. Over time spring will get weaker so trigger will feel lighter. Over time the trigger will polish itself.

I would advise to steer clear of Apex triggers. You have to file some of the frame with a stone. I personally find that not a good thing. I would not want any stone taking fiber away from the frame period. If you are looking to get a striker fired and a trigger mod, go with a Glock 34 like I have. GLocks are way better than the MP Pro for competition.

It appears that it is only the Aluminum Apex triggers that have issues. I have installed 3 polymer triggers and one aluminum trigger. I had no issues with the polymer triggers. I had lots of issues with the aluminum trigger and finally ended up taking it to the gunsmith to finish the install. He too had issues. On the polymer triggers there was no filing involved at all.

I should note that we have 2 M&P 9c's and 2 5" Pros, with a 5" C.O.R.E. on the way. On both the Pros we have the FSS kits in (polymer in mine, Aluminum in his) and in both the 9c's we have the DCAEK kits in with polymer triggers.
 
I have both a standard 9mm 4.25 and a .40 5" CORE. both factory triggers had a slight gritty feeling. I installed an Apex FSS and trigger kit on both of them and haven't had a single problem. they both fire beautifully.
 
What is sad here is that at any gun show, there are at least 3 certified Glock armorers doing trigger upgrades for the price of a decent dinner, using factory Glock parts. Why is there no one doing this for S&W guns? Not enough demand? I joked with one of them yesterday, asking him to go to the Burwell site & familiarize himself with what to do. He could then practice on my gun. This guy rips a Glock apart, & does his upgrades in minutes, & the customer doesn't have to pay $100 for the trigger parts. $30 max for all the trigger parts, plus labor. It's actually quite entertaining how this one particular guy does the work. The customer gets his gun back with all the Glock upgrades, & is entertained as the work is done. Why can't people do this for us M&P guys? GARY

Because this isn't true. Maybe at the gun shows where you go there are a lot of Glock guys, but I don't see that around here.

Sounds like an opportunity. Why don't you go through the armorer's class, become certified and then offer this at the gun show? You could make some money.
 
I bought the Pro 40 a couple of years ago. My trigger was very gritty also. I put Flitz on all the trigger contact points and worked the trigger until it smoothed up. I have now installed an Apex sear and my trigger is great. Yeah it stinks it wasn't smooth out of the box but I'm happy now.

Doing Glock upgrades is FAR EASIER from my expierience. The Apex stuff is not drop in on some pistols. The biggest difference is the way S&W designed the drop safety. Except for CORE pistols, you have to remove the rear sight. That can cause issues on some pistols. It did mine. I got my sight off but stripped out my sight tool trying to get it back on. I spoke with 3 local gunsmiths who would not touch it. So it has been sent to a fella in AL. to get the sight put back on.
I know many folks here have had no problems installing the Apex kits but I know some have so it really is hit or miss. Sight relpacement is a bugger on M&P's

It is true here in the Dallas/FW area. Glock armorer at every gun show I attend. No S&W armorer at any show I have been.

Because I am already at all the local gun shows selling guns, so I don't have time to work on guns. GARY

Well, I haven't done all the different upgrades, but I have done some. I find the M&P to be easier to work on. Then again, I haven't installed any parts on a Glock in a while. I can install the Forward Set Sear kit (probably the most involved kit) in 15 minutes or less.

Maybe I should start doing this at gun shows? Hmmm....

It would have taken me about 15 min if I could have got my rear sight back on. Now the Aluminum kit I tried first was a complete nightmare! The pin is far to tight in the trigger.

Have to disagree with you on this. You don't have to remove the rear sight to remove the striker plunger on a Glock. It takes a hammer and punch to completely dissemble the M&P, it only takes a punch for the Glock, no hammer. The Glock is much easier to work on then the M&P. I have both Glocks and M&P's. They are both good products but being easier to work on is not one of the advantages of the M&P.
 
I have been wanting a 5" 9mm Pro Series pistol for some time now. Just this weekend my local dealer got a 4.25" Pro 9mm in and I bought it to add to the 4.25" .40 and 9mm Shield that I have until I could find a 5" Pro 9mm.

My disappointment comes from the gritty feeling trigger this new Pro 9mm has. My Shield feels a little gritty as well but not as bad as this new Pro. My standard M&P .40 trigger has a pull that is smooth as silk. I would have thought that the extra $$ for my Pro Series 9mm would have given me at least the same if not better overall feel than my 40. This is not the case.

Being new to the forum I hope no one is offended by my bringing this up. Is it a break in thing? Is it the norm for this series of S&W's? I am not so sure I want another M&P if this is the norm. I currently own 2 Sig Sauer's, a Glock, and 4 Ruger's and not one of those brands has had this gritty feel to thier triggers.

If anyone else has had a similar experience, will S&W do anything about it or should I just trade them off for something else? I love the ergonomics of the pistols, but not at the cost of poor trigger performance.

Many thanks for everyones patience with me post on this post :) I would appreciate any guidance you veterans could offer me.

The components in the PRO are the same as what is in the latest generation of M&P's. It used to be that the PRO got the Performance Center Sear and the standard M&P's didn't. That is no longer true.

Gritty feel generally comes from the striker block (specifically the spring having too much tension on it). Either polishing this part and cutting down 2 coils off the spring OR buying the Apex USB solves most all of the grit feel.
