New M&P owner jam question

[PMoore]

I took my brand new M&P 9mm out for first time tonight and it jammed on the very first shot. Is this common?


I was all stoked to put 50 or so rounds through it tonight and was really bummed with only getting one round through it. I couldn't clear it till after I got home. The slide would not move back at all. I saw where someone suggested putting slide against table and putting a lot of pressure on it to clear it. This worked but I don't want to rely on this to clear it every time if this is a recurring thing.


What can I do to stop this from happening. This was not a case of limo wristing either.


I'm glad this wasn't a self defense situation or I'd be in a world of hurt.


Any suggestions would be appreciated.


Thanks.

If you put a full mag in, can you rack thru all the bullets with no issues?

Actually quite uncommon. What type of ammo? Shouldn't really matter but curious. I'm betting it won't happen again. Let us know.

Did this happen after you fired a round or while cambering the first round?

Did you clean it before you tried to fire it?

We need more info before we can help you.
Did you disassemble and clean and re-lube the gun before attempting to fire it?
Was the ammo new factory or remanufactured ammo?
Did the first round fire and not extract or did the first round not completely feed into the the chamber and then get jammed partially in the chamber?
It may sound pretty basic, but CONFIRM that you have the correct caliber ammo for your gun. You could have been given the wrong ammo or the ammo could have not matched the box markings.

That's why they call them semi autos. Auto semi of the time.

The round you pulled out of the chamber after you got the slide to come back looked normal ? There's not a bulge in the barrel ?
Have you gone out and shot it again since ?

Just a guess, but when the slide doesn't want to move it could be that your RSA (recoil spring assembly) came out of it's notch and got cock-eyed.
If you cleaned it before you took it out ( or if it was put together wrong at the factory) it's possible the RSA was not where it was supposed to be. Look in your manual and it will show you the proper notch under the barrel where it should rest when assembling.

I had that happen on my first M&P Shield. Got rid of it shortly thereafter. I have since gotten another Shield. I was told that it had something to do with not getting the guide rod and recoil spring centered if you take it apart.

A couple of days ago, I watched a video that stated the little bar that you push forward in the magazine well to disassemble the weapon gets pushed too far to the right and out of position. You have to move it forward and back into place. You can do that by reaching into the magazine well with a pencil or something similar.

I've not had it happen to me with my current pistol. However, I replaced my spring and guide rod with a one-piece stainless steel guide rod. Don't know if that helped the issue or not.

I don't use the yellow sear deactivation bar when I disassemble, so hopefully it won't get pushed out of place.
Just another part I don't need.
I'm capable of checking that the pistol is unloaded, then pull the trigger to get the slide to come off.

Some weren't comfortable with pulling the trigger to disassemble, or some tried to disassemble with a round in the chamber and had a ND, so S&W did a redesign so you could push the lever down and not have to pull the trigger.

Wow, sorry for your experience, I've never had that happen with any of my M&Ps. My first thought was did you disassemble, clean and lube before you went to the range? Next question would be about ammo-factory or reloads? And finally, was it reassembled correctly? These questions have already been asked, and there's a reason for that. We all hope it's something simple and you get back to the range to shoot another 49 rounds

FALSE!!! S&W did focus groups with prospective customers on what they wanted in a semi-auto service pistol before they did the M&P design. One of the things the customers were very insistent about was that the phrase "Pull the trigger." did not belong in field stripping instructions. Most people concur.

Please don't encourage folks to ignore safety instructions. If you want to, that's your choice and your responsibility.

The one item that did change after initial design was that the flush to the frame slide stop that was supposed to be standard* got changed to the intended to be optional-at least for LE sales-slide stop with a slight extension. When they put prototypes/pre-production pistols out for test and evaluation the optional slide stop won out. The original design made malfunction clearance darn near impossible.

* The guys who favor using the support hand to release the slide from locked back prevailed in design. They didn't in the market place.

If you don't want to pull the trigger when field stripping that's your choice. I choose to do it instead of fiddling with the lever.
No, it's not in the instructions, but it works for me.
