M&P 22 FS Failures
I'm having a consistent problem with my M&P 22 FS in which with each of my 3 magazines I am getting either a failure to fire or failure to feed at least 3-4 times per 12 round magazine. Typically the second round in the magazine will never fire and after that I will get a few more either failure to fires or feeds thereafter.
I've only been using Remington Thunderbolt, Golden Bullet, and Winchester hollow points, all of which perform the same in the pistol.
This same ammo runs fine in my M&P 15-22 with no failure to fires, or feeds.
So I ask for the wisdom from you folks before I take this up with S&W.
Oh, I purchased the pistol new last January and have ~780 rounds through it.
The problem has always been there but not nearly as often as my last two times of use.
Thanks in advance.

There is something about Remington 22s, I hear from others many think its the bullet shape, if you are going to have a feeding problem Remington is the most likely one to have that problem, my 22 cal AR won't feed Remington's at all, constant jams, but my Ruger 22/45 feeds them perfectly. 22 cal firearms can be very finicky about feeding different brands of 22, like I said my 22 AR is one of those. That doesn't explain the failures to fire, its possible they aren't seating fully in the chamber, if they aren't 100% all the way in the chamber they usually won't fire, most of the firing pins energy is spent seating the cartridge deeper in the chamber, a dirty chamber can also cause this, a thorough cleaning with a bronze brush might help. Try various brands, you may find a different brand that feeds 100%, I know that's difficult because 22 is still hard to get.
If all else fails, call S&W.

First and foremost, is that almost any gas operated .22 rifle or pistol can be very picky about what ammo it likes and dislikes. My full size M&P22 will choke on Federal AutoComp, but feed Winchester silverbox just fine, as well as running Remington Subsonics with a can. Sometimes it will even run AutoComps, depending on the lot. CCI's have never been a problem either.
Polish all the surfaces of the slide rails that you can, and use the best ammo you can find. Clean your mags too, sometimes they are the problem and not really the ammo.
The only .22 I own that feeds everything every time is my 1906 model Winchester pump and my Savage 24 .22 over 20 gauge... All the semi autos have their own preferences, with is a pain in the butt when .22 ammo availability is what it is today.

I will admit I've never actually laid my hands on a M&P 22, I think its safe to say its a blowback, recoil operated 22, I've never seen a gas operated 22 rimfire of any kind. Don't worry, we all have brain farts from time to time, I certainly have!

Just forget the Remington .22's and buy Federal or CCI ….I have two M&P .22 and have never had a issue with either with Federal's….two failure to eject with CCI when one was going through initial 50 rounds…no problem since..

I have not modified the very smooth grip surface yet. About 95 % of the rounds have been Federal Auto Match .22LR.
I only mention this, because of your story; almost always the second round, with most of your magazines and has been consistent since your ownership whereas the same ammo run thru a rifle with typically better operator support functions fine.
You might consider experimenting with how much / too little grip pressure maybe affecting your malfunction rates.
