Any M&P FPC Shooters Out There??

Unlike in past years when S&W has sent me parts because this is a new product and they want to see what's going on so it'll be headed back to the factory in a few days.
If I had waited the three weeks before I'll have one that will actually function I would have gotten a better gun and probably at a lower price as they are dropping almost daily.
Cheers

Firing pin issues FPC

I recently purchased the FPC. Had no issues the first time at the range. The second time I went, I had failure to fire after about 25 rounds. No impact on the primers. Upon takedown, the firing pin fell out of the bolt. Smith and Wesson had me return firearm to them yesterday. This appears to be a problem with the tiny retaining pin dislodging. I am concerned with reliability in the future. In addition, I anticipate no easy way to remove this firing pin for cleaning given the design of this tiny retaining pin. We shall see.
 
Just unboxed the FPC today. Fired 10 rounds with no issues and then refused to fire again. I'm starting to think S&W doesn't like me. I bought a Performance Center Victory that made two trips to the mothership and still wouldn't work. Luckily I found the problem and fixed it. Looks like this brand new gun goes back as well; hope they have developed a fix for this 'cause I don't think I should have to work on a brand new gun...

I was waiting to see if people had problems with this gun before I bought one. Unfortunately people have been having problems, usually failures to fire like yours. I hope S&W fixes your gun quickly, let us know what the diagnose was when you get it back.

Not sure what is going on but there have been too many reports like this. I really like the FPC on paper but don't feel like rolling the dice and getting one that refuses to fire.
 
As I only saw and had mine to examine I can only speak of its issues.
There is little doubt on mine that the firing keeper pin was not properly installed and DID NOT back out from firing (unless it did so from a few factory rounds) as it failed to fire on the first round.
On my gun the retaining pin had just entered the firing pin channel by a few thousands of an inch.

Roll pins are used to keep firing pins and extractors in place in millions of guns so I don't believe that the use of a roll pin to retain the firing pin is the problem.

If I had it to do over knowing what I know now I'd take the bolt out, clean any oil off the retaining pin and channel with break cleaner and compressed air, make sure the roll pin is seated to the proper depth and put a drop of LocTite 243 in both ends of the retaining pin channel, let it dry, reassemble the gun and enjoy shooting it.

I can't imagine how "cleaning and lubing" the gun would have any benefit on an improperly installed roll pin.

Again, I only speak of the problem with MY gun.

Very poor assembly process!!

Mines been running just fine. Got over 800 rounds through it now with no issues. Gets cleaned and inspected after every outing.
 
I had a very similar experience. Shot about 30 rounds and it stopped firing. Had the gun smith look at the firing pin with me. We cleaned it up and got it free and was able to get it shooting.

Took it back to the range a few days later and after 20 or so rounds it happened again.

This time we investigated further. It seems the area that the hammer is striking the pin is too soft. (Possibly not hardened enough). As the hammer strikes the area, it is actually deforming the metal and causing it to tighten the tolerance for the pin to move freely.

My pin was not moving back and forth, it was basically binded in the area circled from the metal being deformed and causing the hole to shrink

FPC failure to fire

I bought the FPC on the 22nd of March. Took it to the range last Wednesday. Fired the 17 round magazine flawlessly. Reloaded with a 23 round magazine and....click. Eject chambered round, chamber another....click. Eject round, swap to 3rd magazine, chamber a round click. Inspect all ejected rounds, no primer strike. My range buddy had a S&W pistol so we tested the ammo and magazines in his pistol. Entire 23 magazine fired. Took the FPC home, field stripped, cleaned, lubed, reassembled. Sent an email to S&W. No response. Went back to the range today and had the same failure to fire, no primer strike issues. Emailed S&W again. Owner's manual states not to take down any further than field stripping (which I suppose is why they don't publish the complete bolt takedown or diagram) so I wouldn't know what to look for being missing or damaged. If I don't get a reply tomorrow after work, I'll call and try to talk to a human. I too, watched all the reviews and was pretty excited about this purchase. Seems like the previous advice I got and ignored about not purchasing a "new model" initial release was correct.
 
When you have it field stripped look at the firing pin retaining split / roll pin and make sure it's goes through the firing pin channel and is into the bottom of the firing pin channel .
Push the firing pin in from the rear with a small tool (punch, pin, etc.) and make sure that it moves freely out the front of the bolt and returns into the bolt when pressure is released on the rear of it.
If it isn't properly retained (roll / split pin installed at the correct depth) and if it doesn't move freely that's your problem.

I got the FPC back yesterday.
The work order said, "Replaced Bolt".
I finally got time to strip it down and take a look at it.
It's definitely a newly designed bolt.
No roll pins are used to retain either the firing pin or the extractor.
The retaining pins have a larger diameter "head" to keep them from falling through and they can't come out the top as they are kept in the bolt by the carrier tube.
As they are not roll pins there are no close fit tolerances so they are easily removed for a thorough cleaning of the bolt assembly if desired.
Bolt assembly is now as it should have been, functional!
Nothing inherently wrong with roll pins if tolerances and materials are good.
The new design allows sloppy parts and sloppy assembly to still produce a functional gun.
No doubt the original bolt designer got a raise and was promoted to head of safety mechanisms.
If I get time next week I'll take a couple of pictures and post them.

I was planning to purchase one of these when I could locate one. Now I think I will wait till the bugs are worked out. Almost seems like a recall is in order if a re d signed bolt is being used
 
The new bolt assembly is very well thought out, it will be easier for the assembler to quickly get together correctly, and the previous problem is completely eliminated as it is now impossible for the firing pin keeper to back out enough to adversely affect its intended function (to retain the firing pin).
I bought one thinking that it was good to go but unfortunately it wasn't.
Seeing how the potential problem has been addressed and completely eliminated I personally would not hesitate a second to buy another one or recommend it to someone who wants that type of firearm.
I didn't take the extractor pin out to measure it so I don't know if they are the same or not.
The new firing pin keeper is about .577" total length.
The "head" is about .118" diameter and about .057" thick.
The FP retaining portion is about .077" diameter and about .520" length with a small chamfer to help start it into the small portion of the double diameter (the top portion has a counterbore for the head to stop on) hole.

Thanks for posting the pictures! The FPC is back on my buy list as long as I can find one at a LGS and can verify it has the new bolt. It looks like a great gun but only if it is reliable.
 
It will be interesting to see if all those already sold have to be sent back in, or if S&W will just send out a new bolt assembly.
 
I posted this on another thread a few days I cleaned it from Yesterdays shooting session and went back out today and on the first magazine, something broke inside the trigger housing. The magazine will not see the bolt will not go forward and there’s just something flopping around in there. So there you have it Smith and Wesson. Let me down once again so tomorrow morning I make the dreaded phone call get the shipping label send it off and wait a couple months to get it back. It was fun while it was working. Stay tuned. I’ll let everyone know when it comes back if it’s fixed and if it happens again.
 
I sent mine in 3/14/23 and received it back 4/14/23.

I'm actually glad that it malfunctioned right out of the box leading me to send it in resulting in it getting a much improved bolt assembly.

I put ten rounds through it off the front porch this afternoon and it went bang ten times.

I hope to get it down to our range this week and sight in the Trijicon MRO.

Cheers
James
