It is the hammer reset after an empty mag. I would put another one in and then use the bolt release to go into battery. I would squeeze the trigger and nothing. I would have to pull on the bolt handle and a round would come out but the next time pulled on the trigger it would work. Now mind you, it is next to impossible to use the bolt release. I thought S&W would have learned their lesson on the M&P line by using bigger slide/bolt releases but, for some reason they used flat releases.
Any M&P FPC Shooters Out There??

I also bought a new FPC for steel challenge. 500 rounds and no issues at all. I was wondering if anyone has shot aluminum cased rounds thru theirs and had any problems. I need something a little cheaper cause I plan on shooting a lot
I've not shot aluminum, but a friend has with zero failures. I've not heard or read of any variety of ammo causing failures. It seems they'll eat anything factory, but +P+ ammo or handloads with similar pressure are considered extreme and shouldn't be used.

Hickok45 put up a review on YouTube today. It worked fine with everything except Underwood ammo. The same ammo caused problems in a different FPC that was also reliable with everything except Underwood. I don't remember his saying it was +P+ but the way Underwood loads ammo it might be considered +P or +P+ which supports your conclusion.
It looked like it was failing by the slide cycling so hard it rammed the rounds past the rim in the chamber they normally headspace on so far the firing pin couldn't reach the primer. It looked like it took a lot of force to get the rounds out. Both FPCs worked fine with all other types of ammo tried and the Underwood ammo worked fine in all the other guns it was fired in.

Update---I looked at the manufactures website and they said not to use their aluminum cased ammo in a carbine style firearm. Bummer!
I looked at the CCI Blazer Aluminum 9mm where they say NOT to use it, but they give no reason why.
Not sure why the ammo is fine in pistols but not in a PCC.

Just found a website for aftermarket parts for the FPC. There are some interesting things. I am getting the Buffer-end plug.

I don’t see how additional pre-load on the rear spring would increase the recoil damping. It seems it would do the exact opposite by not allowing as much spring compression by the rearward moving bolt. Also, since the recoil spring and the rear spring work in tandem, the longer plug would also be increasing pre-load on the recoil spring as well. Looks like a gimmick to me.
Okay, shooting the FPC is like eating Lays potato chips, you can't use just one box. It is so fun shooting the gun you can't stop. I put the Odin Works compensator on it and it seems to reduce what recoil there is. Shooting at 20 yards off-hand and I was still putting a big hole in the target.

Anybody running BUIS on their FPC? Pictures, please. Thank you.
You might consider getting a police report listing serial numbers for that incident in case later on you're questioned about it.
There are examples where someone claimed 'a boating accident' but the guns later showed up. LE wasn't happy.
So CYA appropriately.
Out of the box it was a "bear" to pull back. Did a full cleaning to get rid of the storage lube (I think it's a dry storage lube) and then fresh lube. While I was cleaning, I'd take a little break (watching a movie) and just kept running the charging handle back and forth (with some pressure added) on the slide, that seemed to help quite a bit.
After a full cleaning, lube, inspecting each part and reassembly I just kept working it back and forth with everything (bolt, springs, butt back on, re-installed). Didn't "slingshot" the bolt, just road it back and forth so many times I lost count. With the fresh lube and constant cycling, it did help quite bit. Almost a night and day difference. After more break-in firing, it should ease up even more. But, I think it will be a two finger pull charging handle for a straight even pull back charging. Got to remember, these are brand new and have fresh tooling, tolerances will be at there best on this first run. Good thing in my book. Hope this helped.
NOW FOR EVERYONE ELSE. Best suggestion for everyone. READ THE MANUAL FIRST !!! I don't care how experienced or un-experienced you (think) you are. This is a new "animal" on the block. Seems to have a dry storage lube, SO CLEAN THE LIVING DAYLIGHTS OUT OF IT WITH A GUN FRIENDLY CLEANER !!! THEN USE A PROPER GUN LUBE MADE FOR WEAPONS !!! NO DICKIN' AROUND WITH MAMBY PAMBY HOMEMADE CLEANERS & LUBES !!! It has different materials through out the whole weapon. It's a Pistol round, Collapsible, Carbine made for short to (extended) medium range use. Think of it as a Full Size M&P on Steroids.
Smith & Wesson did their homework on this one and come out with an OUTSTANDING WEAPON. SO, don't screw it up cutting corners !!!
That needs to be repeated. Read the manual. Follow the directions.
BTW my charging handle operates just the way I thought it should. Not difficult at all.

More likely Underwood is using too much crimp in an effort to prevent bullet pull under higher than usual recoil. Even a taper crimp that is too strong can cause headspacing issues.
