Man, it would be great if Apex released some trigger components for the new .22LR variant. Nothing's worse in my book than a stiff trigger pull on a .22.



I wonder if there'd be enough of a market for Apex to make it worth their while. Maybe they'll chime in here...

I'd tear my gun apart if I had an idea of how to put it back together...S&W won't send out a schematic on it and I haven't been able to find anyone who's completely broken one down to see what could be done-hence the post...



As this is M&P central, I thought someone would have messed around with one at this point...I guess I could pull it all apart and then send it back to S&W when I can't put it back together....I hope it wouldn't have to go all the way back to Germany....



UPDATE: I emailed Walther in Germany since they build it, but they did not have any other information to share...so I guess it will take some brave soul to tear it down and figure it out..

I'm not a gunsmith but looking at the inner workings of mine its a simmple sear and hammer setup. A good hand on a stone to just clean and smooth would be all it needs. Out of my league but any competent smith should be able to do it without a bunch of parts changing. But on the other hand it should be easy to make prep'd parts to drop in

I tore mine apart to remove the Mag Safety but the gun likes that part in there. It isn't hard to get apart and I plan on working my trigger over as soon as I get some time.

I have a Kimber 22lr conversion kit I use on my S&W 1911 Eseries.......sweet cream butter man...............

I corresponded with Jon Shadwick @ Apex Tactical and they do not offer any replacement trigger components for the 22LR because the "M&P .22 is not a M&P." it's a Walther.

I have a M&P .22 and thankfully after 450 rounds my trigger pull has dropped down to about 4.5 pounds which I am fine with. I did field strip and clean and lube the gun beforehand and that probably helped some.

I've shot the.22 m&P at the range. The trigger has a totally different feel than my M&P 9. The .22 trigger feels like there is almost no resistance to it. Not sure if that's what happens after a lot of shooting or what. Out of curiosity I'll ask the guys at the range tomorrow to get their take

picked up my MP22 yesterday. Checked it out at home, and it looked like it been dipped in oil. I cleaned up all the excess I could and cleaned out the bore, then went off to the range. put a couple of hundred rounds through it without any failures, but did not like the trigger or the magazine disconnect.

Came home and decided to see what was on the inside. Disassembly is not for the faint hearted, but I did successfully detail strip and complete a full reassembly.

removed the magazine disconnector, so can now dryfire without a magazine.

with the parts reassembled into the receiver, I studied sear and hammer for a bit, and noticed that when the trigger is pulled, the sear actually pulled the hammer further down. this didn't seem right, so very carefully took a fine file to the hammer notch and very slightly changed the angle. it was square 90 degree, and is maybe 95 degree now. While doing that, constantly checked fit and interaction with sear. The sear was twisting while releasing and so tried to cut a touch more from left side of hammer notch.

came out great. trigger is smooth and about 3.5 lbs. there's a small spring that the keeps the sear engaged. I plan to replace that to get the pull up to 4.5 to match my m&p40.

Welcome new member, FYI do not dry fire any rimfire on an empty chamber, use of a snap cap is highly recommended otherwise damage will occur to the firearm.

I just picked up my M&P 22 and did much the same thing as you have done. Detail stripped and cleaned out the goo. I polished the hammer/sear interface, though have not changed the angle. I also polished/deburred the trigger connector bar, sear sides, hammer sides and other various interconnected parts.

The disassembly/reassembly is not difficult. It is tedious and requires careful precision work. There are multiple springs, pins and parts to remove/ reassemble without losing any and remembering where they all go.
Smith & Wesson does not make this any easier by failing to provide any detailed schematic diagram of the gun and its parts in the manual. I expect this is because of the lawyers and other products liability people not wanting folks to work on their own guns.

Upon reassembly, the trigger pull is about 3.5 lbs and smoother. I wish there weren't so much take-up in the trigger, but given the mechanism's design and the need to have movement in it to first disengage the firing pin block before releasing the hammer to fire, I suppose it's the nature of the beast. I don't own any M&P center fire pistols to compare with, but the trigger now feels a lot like my Glock 19 trigger with a 3.5 lb polished connector. Hardly even close to my S&W Model 41 or the hand-fitted trigger in my Model 63 stainless .22 revolver, though I can live with it.

I also have removed the magazine disconnect. I don't intend to dry fire this gun, but I find them generally anoying, I did leave intact the manual safety lever system. I don't really intend to use it, but it doesn't get in my way and it is there in case I ever should want to.

Smith Shooter

Right. The centerfire M&P's are striker fired guns and the M&P22 is a hammer gun. The centerfire Apex kit is not at all compatible with the M&P22.

Now, if the M&P22 becomes popular enough, there may indeed be aftermarket action parts available like there are for the Ruger MkII and Mk III series.

Just picked one up yesterday. Aside from needing some light sanding in a few spots, I think everything functions great. I'm going to hold off until I can visibly verify spots that need correcting after a few hundred rounds.
Compared to a Ruger 10/22, this pistol is like a BMW vs a Chevy. Germany isn't going to build something that can be greatly improved by American made parts, with the exception of the sights.

I just took apart mine to remove the left side safety lever and having a heck of time reassembling. I noticed there is a small spring that came loose, about 1/4" long and 1/16" in diameter. Where does this go? And the metal plate attached to the thumb safety rod, can I just remove the entire thumb safety assembly including both levers, the plate and the rod?

Edit: the spring goes in the lower part of the trigger. I needed to remove the roll pin and place it back in. Another mystery solved.

I've done a bit more to mine. I wanted to move the sear release back closer to the stop in the trigger guard.

beware - There are no replacement parts available and this will void any warrenty

After some careful measurements, I filed the trigger bar such that where it engages the sear pin is not vertical but is now angled slightly forward.

This increased the length of pull to about 3/16 inch and reduced trigger pull to 2 3/4 pounds.

The gun is now amazingly quick to shoot!

Anyone i've let try it says wow.

I even used it at a man on man plate match and took first place.

the M&P22 is no match for a model 41 accuracy wise. but a lot of the guys at the match had 41's and some of them with optical sights. The M&P22 is lighter and quicker to get on target.

And I also have a glock 19 with a 3.5 disconnect. I like my M&P trigger way more. Though I will concede that take-up is a bit long. Maybe reducing take-up should be my next project.

My M&P22 had a trigger pull of 6lbs new. All I did was use an Arkansas stone on the hammer, where it contacts the sear, using a lighted magnifier. You have to be careful to keep the wear pattern straight. When done, I put a little dab of aluminum anti-seize on it. I now have a very smooth trigger pull of just under 4lbs.
