Call back s&w. They need to replace this oneOk problem with mine was not the spring. Take a look at the top of my barrel.
the barrel does not drop low enough when the slide goes back. My gunsmith just smoothed this out and rounded the top inside of the slide where this was getting caught up. he said he had never seen this before. I sent this picture to Smith and Wesson and they said it looked like normal wear...................hardly.
I have about 1,000 rounds through this gun.
Now it is functioning fine, but I will keep an eye on this to see if it
starts to dig in again.
Take a look at the top of your barrel and see if there is a "ledge" being dug into the top of it.
If it's new and it's sticking tap the end of the barrel with a rubber mallet when the slide is locked back.
If it pops shut (like mine did) you may be looking at a similar issue as I have here.

it's all smoothed out now so I am going to keep an eye on it. I shot 50 rounds through it today and so far so good.

Did the gunsmith look at the lug? If the barrel/chamber is being pressed up against the slide, and that's what's causing the gouge in the top of the barrel/chamber, then it's an issue on the bottom of the barrel; most likely the lug. Some material may need to be removed to make it fit correctly, but not from the top.

he did not, I'm actually on my way to the range right now. I'm going to
keep an eye on it.
I sent this picture to S&W and requested a new barrel, I hope they don't blow me off.

I just purchased the Shield Performance Center 9mm and this happened to me on the range today. I got through 2 clips and the slide locked up and I could not get it to move forward. Very disappointing and worrisome as I purchased this to be my carry gun. Got home and somehow got the slide to move forward so field stripped. It does seem like Rastoff's post might be on to something since the slide was really stuck and I could not get the slide to budge at the range. Seems to be fine now so will hit the range again this weekend to see if it happens again.

I too just purchased a 9 mm Performance Center Shield and took it to the range for the first time today. I was shooting 115 grain Blazer Brass FMJ. Halfway through the 3rd or 4th magazine, the slide locked to the rear and wouldn't budge. I released the magazine and fiddled with it for awhile, inserting empty magazines, etc. and finally got the slide released. I fired another 3 or 4 magazines and it locked up again.
Once at home I fiddled with it some more and finally got the slide released and attempted to field strip. I had a heck of a time getting the slide locked back. The slide lock lever didn't want to move. Finally got it stripped down and cleaned and lubed. After reassembly, everything seems to function properly, but have not shot it yet...hopefully this weekend.
There is definitely something going on with these pistols.

We've heard of a few of these recently. I wish someone would post a pic of the gun locked back.
After field stripping and cleaning I was anxious to see how it would perform so hit the range earlier today. I still had the issue with the slide locking to the back. It seemed to do this toward the end of the magazine (8rd around the 7th and 7rd around the 6th) so I released the magazine and did what Rastoff suggested and bumped the muzzle against the pad at the range and it seemed to release it every time. Was still frustrated it was happening but at least I was able to get it back to normal to shoot more rounds through it. It seemed to be getting a little better after shooting more rounds as I noticed it was finally getting through a full magazine and not locking up on the last round. Still confused as to whether it could be what Rastoff was saying the barrel getting pinched or a problem with the feeding from the magazine. I am guessing more of a pinch problem. Rastoff I plan on hitting the range again this weekend so if it does the same problem I will take pics and post. I am also going to call S&W on Monday to report the issue and see what they say. Sorry for the long post

If bumping he muzzle releases the locked slide, I'm almost positive it's the chamber/barrel lug that's getting wedged in the slide somehow. I'd love to see it in person.
It's now simple......
After reading the excellent posts and you having done what was reasonably possible, the Mother Ship is the answer. Calling them is always the best way to contact them. They will send you a shipping label and it goes to the factory. If it's a defect they may fix it for free and these are turned around fairly quickly and you should have your gun back in about two weeks tops. You may want to include the picture in the package. They usually want to see the whole gun and are unlikely to send a barrel because if that's not the problem it's a waste of everybody's time and money.
If the slide is sticking back with nothing visibly wrong, it's not right and needs to be checked.
I had an older Shield and complained of a too tight chamber. I sent them the gun and about 10 days later it was back with a new barrel.

I have to agree with you Rastoff that it is a pinching problem possibly during the ejection process since the slide goes further back than the normal slide lock and I can physically see the next round in the magazine which could not get loaded. Rwsmith you are right it needs to get checked by S&W and appreciate the information you provided in dealing with them. I will also update after speaking to S&W on their thoughts and if they have heard about this issue before. Thanks to everyone for the guidance.
Went to the range yesterday and put about 100 rounds through it and it performed flawlessly. It fired accurately and going through magazine after magazine showed me why this is such an awesome little gun. Just need to get over this slide issue. Still going to call S&W and see what they have to say.
Hi everyone, new member here from Reno NV.
I recently bought a new S&W M&P Shield 9mm from Cabela's here in Reno. On my first trip to the range I experienced, several times, the same issue that others here have described: my slide would lock way back, past the slide stop/lock, in the furthest rearward position. A heavy tap forward on the back of slide would cause the slide to return to battery.
I sent my new pistol back to S&W about 3 weeks ago. Today I contacted customer support--they told me that the smiths replaced my barrel. I got my shipping notification this afternoon.
Hopefully it's been fixed. I just wanted to let everyone know that this issue is definitely a thing.

Teebiss thanks for the information.
I just contacted S&W and told them about the issue and asked if they have heard of this before. I received the typical customer service answer of no, sounds like an anomaly and that I should send it in to get looked at. I just got my shipping label So will be sending it off.

I just purchased my 9mm Shield last week and yesterday took it out to the range. I had this same sticking slide issue three times in 200 rounds. A couple of taps on the rear of the slide would dislodge it. It became very obvious the slide was binding somewhere. Unloaded cartridges were still in the magazine, and the slide lock was not engaged.
Patton thanks for sharing. There definitely seems to be some sort of issue as we should not have to be tapping the slide or muzzle for it to operate properly. I sent my gun in last week and just received my RMA number today. I say don't take any chances and send it back to S&W to get looked at and/or repaired. Hopefully S&W sees there is an issue if quite a few people are having the same problem. Just my 2 cents.
Just got some. I hope they are good enough. I wasnt sure what exactly to take pics of. I also took a short video that may or may not be helpful. I dont know the prefered merhod of uploading pics without slowing the threads load time, or making multiple posts Been a very long time since ive used a forum.
Im not too new to firearms but i know i dont have the level of knowledge i should or know all the proper teminology so bear with me.
This is my second 9mm shield. My first never had this issue. This one purchased new, brought it home and cleaned/oiled everything prior to firing the first time. 3 days ago was the first to shoot it. It made it through 3 rounds before the slide stuck all the way back. No play in it to get it to release so you have to hit the back of the slide to return it to battery. Another 2-3 rounds and it did it again. Took it apart to see if anything stood out as being off, or catching and didnt see anything so I re-oiled it and tried again. This time it would get through all but the second round. I showed it to a couple shield owners and they were clueless as well as to what may be causing it.
Took it apart today to check it over again to see if i missed something and there was one thing that stood out to me. Im not sure what this part is, whether its slide guides or what its proper name is but it will be my first 2 images. On the top is normal smooth wear, but on one side there is a gouge, but i cant see anything on the slide that could be causing this. Took it out and made it through 30 some rounds without issue before it locked up again. One of the images i have the slide lock pushed up to show how far back it is sitting.
