M&P Slide Locked/Jamed

[Rastoff]

OK, here's the solution.

The barrel/chamber is wedged between the slide and frame. The barrel should be loose and you should be able to wiggle it around. Here is what I recommend...

With a full firing grip on the gun, drive the muzzle of the barrel into a piece of wood or the carpet with a solid backer. The idea is to move the barrel backward. This should un-wedge it. Be ready for the slide to slam home.

I can post pics of the process if you need them.

Thanks. So, before my first sip of coffee this morning, I drove the muzzle of the barrel in the oak edge of my work bench. I was slamming it pretty good. Still stuck. I wasn't soft on it at all. This would seem like a solution. I may try wacking the muzzle with a plastic mallet I have a little later. This is one stuck slide!

I don't have an m&p9, (I have a shield), but does that yellow lever thing next to the ramp look out of place or is that normal?

It looks like the sear deactivation lever in my shield but my lever isn't located there. It's also not in Bob's picture.

Thanks! Not sure, I defer to others that have an M&P - I dont have another one to compare it to. Anyone have any thoughts?

if the barrel is jammed under the slide it will probably have to go back to smith and wesson even if you get it unjammed so I would just send it back and let them fix it, it seems to have jumped off the track I wouldn't shoot it if I got it back together with out a smithy looking at it. JMO

The sear deactivation lever is on the other side of the opening. That yellow thing is the spring for the slide lock.

So it appears that you are at the point of either sending it back to S&W, or............ you could knock the trigger pivot pin, the takedown lever, and the two block pins out and pull the slide up and out of the frame with the sear and trigger blocks. You will end up with a lot of pieces but it will come apart that way. I wouldn't do that unless you have someone who is familiar with M&P's to put it back together. (not real difficult, but for someone who hasn't done it, maybe not a good idea).

Sounds like its time to send it in.

Thanks to all that have helped with this. Great group, glad I own several S&Ws, but mine are revolvers. I got in touch with the owner, a friend, and recommended he send it back to S&W after calling them and getting a shipping label.

Thanks again!!

Well, this is frustrating. I'm almost positive that the barrel is too far forward and is wedged between the frame and slide. I wish I was closer because I'm sure we could get it fixed. This is not the first time I've seen this.

The one thing you can be sure of, S&W will get it fixed up.

This is not the first time I've seen this.

This thread was a fascinating read. The question I have at this point is what would have cause this, did something break inside to make it go out of kilter ? And if something did break inside why and how, reloads ?

No doubt S&W will be fascinated by it as well. As a new convert to the semi-automatic platform (who picks it up today in fact) I'm beginning to here the revolver calling my name again.

I certainly want to give it a fair shake though and not let panic get a hold of me to tight. But it's shows how many different things can possibly go wrong, and here I thought ammo jams where my biggest concern.

No doubt at some point after I get mine broken in I will be carrying a revolver again as a Bug. The good thing like you said is S&W will make it right and it won't take 2-3 trips back either.

Samuel P. Morris,
This is very uncommon. Probably the only reason I've seen something like this before is because I see hundreds of guns every week. I'm Vice President of our local gun club and I'm a firearms instructor. So, I probably see more guns in use regularly than the average person.

I have seen this before, at least I think I have. Without examining the gun personally I can't be sure. It was not with an M&P though. The gun I saw it on was a Ruger LC9. It's a freak thing and very rare. I'm not sure how it happens. It seems to be a timing thing between the slide and barrel movement.

It is very unlikely that you'll ever see this in any gun you own.

I saw a video on youtube with a very similar situation. They had fired a hot round and the barrel actually swelled almost imperceptibly, causing it to seize the slide in exactly this fashion. I'd definitely send it to S&W for a full diagnostic.

Often a bulged barrel will prevent the slide from traveling forward. Take a look and see if there is a ring in the bore, about where the front of the slide is sitting now.

I found another thread that has a picture with a slide stuck locked back and the barrel perched higher than normal. In that particular thread the barrel became wedged against the locking block because the gun had been reassembled without the RSA in the slide. Different problem from the OP's, but it reinforces the theory posted earlier that the barrel is wedged. The thread gives advice on how to remove the striker and several pins to allow the slide to be successfully removed:

Hey Bob, I attached three pics, let me know if you need additional view. Thanks!

From the pictures it looks like one side of the slide may have came slightly off track, can you post a closer picture of that slide release lever?

I share TimmyRay's view. I only have a Shield, and my slide, when pulled all the way back and locked by the slide lock, is level to the frame. The pic above seems to show the rear part of the slide is lifted up, like it jumped from the rail?

At this point, looking at all the posts. Not knowing much, my guess is a recoil spring issue.

I'm gonna lurk until this is solved, if you don't mind. Always up for some education.

This might not be anything and I may well be wrong but I noticed this from your pictures compared to what mine looks like.

On your comment #26 the last picture in the row, I noticed the spring on the trigger bar looks like its twisted. And appears the bottom of the feed ramp is bound up with it

I don't have a shield but a 40c and my trigger bar I would think looks like yours the way the spring would attach to the trigger bar anyway. Mine clearly shows the spring looped through the hole in the trigger bar and then going straight back . Yours looks like it twists to the right . could it have broken binding things up ?

I believe this is the picture you're referring to:

The spring and trigger bar are fine. It looks wrong because the chamber/barrel is not as far back as it would be. The feed ramp is not bound up in the trigger return spring, it just looks that way. It's a matter of perspective.

 

[BIGMAC116]

Is there a bulge in the barrel stopping the slide from actuating?

 

[mod57]

OK just a thought, That pistol looks like it has an IL. Now I don't know how the ILs work in the M&P but could the possibility exist that it is some how locking things up?
