I purchase my 9mm M&P Shield just 3 days prior. It has never been fired but earlier today my weapon began jamming for some reason. I am far from being a gun expert but I do know when there is a serious issue that will require a skill set beyond my own good cleaning or fixing my sights. This is extremely concerning since it is yet to be fired and when making the purchase, I asked for the most reliable pistol and least likely to jam even if neglected for some time and hasn't been cleaned in months. They handed me this Shield. I have owned 3 other M&P's and enjoyed them very much because it's always fun shooting a suppressed.22lr with subsonic ammunition. So I didn't hesitate or question the guy at the gun shop and instead handed him my CPL and credit card. I walked out with the gun, the DeSantis Wuick-Chec leather holster, and a box of range ammo (cheap, 115gr, not recommended for defense).
The last few days I have been dry running some of the ammo through the chamber via a S&W stock Shield extended 9mm 9+1 clip. After clambering about the 35 to 40 rounds, it jammed. I was absolutely shocked. I knew that I had some cheap ammo but this certainly wouldn't cause a jam like this.... Or could it? The rounds all continued to jam with the rear end of the bullet caught low and the tip/projectile was chambered inside the barrel but slightly st an angle (due to the rear end being stuck). When atemptibg to unchamberbthe very first bullet that jammed, it ended up coming apart and the gun powder spilt all over the magazine, bullets, chamber area and a little on the barrel. I quickly cleaned it up before attempting to continue to chamber another round. I believe I did a decent job. But the ammo all continued to jam and the guns slide would continue to close 75% of the way before stopping. It does not close any further and the bullet will not slide upwards any further either. I am afraid of messing around with this gun considering I haven't taken one apart before. I have only worked with the M&P .22's. But I just can't seem to figure out what exactly is going on. Can you guys help or should I just bring it to the shop I bought it from and have their blacksmith look at it. I'm afraid that's gonna cost me a ton.

Thanks guys.

First, did you clean and lube the pistol before you started your hand-cycling? Second, that looks like steel-cased ammo. Third, cycling by hand is never going to duplicate the functioning of the action in live fire. Finally, I'm not aware of a stock 9-round mag for the Shield -- only 7-round flush-fit or 8-round extended. Are you sure it isn't an aftermarket mag or a conversion, like MagGuts?

Clean and lube your pistol thoroughly, get some halfway-decent brass-cased ammo, and take it to the range and see what happens. I'll bet it works.

If It doesn't, then follow up on warranty service with Smith and Wesson. It shouldn't cost you a penny.

it actually looks like federal or blazer aluminum. Steel is slightly shinier (not as shiny as the nickel stuff of course).

to the OP...

1. Don't hand cycle ammo over and over again, you probably got some bullet setback or it's taken a beating with all that hitting of the feedramp and widened the neck a bit and is causing it to jam. Dry firing and hand racking the slide is fine without ammo, but don't hand cycle except to chamber the first round. cheap range ammo is NOT meant to be chambered more than once or twice

2. hand cycling will NOT replicate the same forces and momentum that firing the gun will. throw away any ammo that you've been hand cycling multiple times and get a box of brass or aluminum ammo and go to the range and FIRE IT.

3. make sure the gun is lubed and cleaned before going to the range. some shield's come dry, others come with preservative lube from the factory. wipe down and lube away with any good gun oil (just not remoil, that stuff is garbage).

your description of the shell coming apart with the powder spilling out means that round was beat to **** from so many chamberings. Look at a good youtube video of how to take apart the shield, field strip it and clean it out like you would any other semi autio, and reassemble then LEAVE IT ALONE when it comes to chambering ammo until you go shooting. (leaving it empty and drying firing for practice is more than fine though)

Wow! Stop what u are doing! Discard the junk ammo you ruined by dry racking it, don't blame the gun, take responsibility for doing something you should never have done. Dry racking live ammo is a total no, no.

Buy some good ammo, go to the range and enjoy shooting your new gun.... It's that simple. It's sad to see another thread started, knocking a great gun for something it is not.

Take a close look at the rim of that ammo you have been hand cycling and I expect that you will see the cause for your issue, your cases are all chewed up.

As has been noted what you have been doing is something that you should NOT be doing Not only is it UNSAFE you also cannot duplicate the forces and slide velocity that live fire produces.

BTW, do NOT try and say you were doing this safely. It is a 100% guarantee that do this long enough and at some point you will end up "brushing the trigger" which WILL result in the gun firing. My reaction when I read what you were doing was "YIKES". I expect that future posts will be a bit more forceful.

Do your self a favor leave the gun in the box and take a gun safety course be fore something happens that will haunt you for the rest of your life.

How about an update, OP?

I have a close friend that lost his left index finger due to a ND w/a semi auto pistol. You're headed for trouble and no one here wants to see that.

I've noticed an increase on the amount of new post specially from new members having issues with their brand new guns just because they don't know what they are doing and then they blame the gun. Get trained, and read your manual before doing anything stupid.

It's never been fired but is jamming?
Start over please with some quality brass cased ammo of a quality nature. As suggested, basic take down, clean and properly lube first! Visual inspection for any stray particles lodged somewhere.

And, is that an aftermarket magazine you are trying?
Shoot the gun at the range, I believe every gun has a break in period, I am a reloader but will always run quality factory ammo for at least 100 rounds to break in and study the gun function.

In a polite way, you may be the culprit in the problems that you are currently experiencing and I think you can straighten them out on your own
Good luck.............Love my 45 Shield!

Lay the gun down and back away slowly before you do some damage. Get some good ammo and a factory mag. Take it to the range and shoot it before making any more assessments.

Reread post 3. Addendum 2. Memorize!!!!!!

I'm not going to duplicate what everyone has already posted. Some very good advice in the preceding posts. Post #3 covers it all.

Sorry to poke fun, as your advice and everyone else's is very good, but your specific terminology is off. You can't dry fire live ammo, :-), only hand cycle it (dangerously) as mentioned elsewhere.

Opps, good catch, sorry, wrong terminology.. I fixed it.. got caught up in the insanity of the post...

Seriously these Shields have a feeding problem, not all but some. Mine got sent back to S&W after 300 rounds, occasionally miss feeds. I've never owned a gun like this as far as problems go. I've had my Sigma for 7 years, never once did it fail to feed using all kinds of ammo.

I have just the opposite experience. I have a Shield 9 and a 45. Both feed flawlessly. I had a Sigma that wouldn't feed no matter what I tried. I sold it.

Just waiting to happen

Yikes.

As the others have said: stop. Seriously, stop.

The live ammo you've been cycling is probably suspect at this point due to bullet setback: dispose of it properly, all of it. Find someone who reloads, give it to them so they can pull the bullets and dump the powder.

Clean the gun, buy new ammo, go to the range and fire the gun.

Getting some proper instruction probably wouldn't hurt either.

Best suggestion yet. Much better advice than to take it to the range and shoot it because, from the sounds of it, the OP might hurt someone else or worse.

Definitely, I went to the range last week while walking from the car to the range saw this guy coming out from the gun shop going to the range.
He was first in line to register and I could tell he was a first time shooter/gun buyer, even the guy at the counter asked him if he knew what was he doing !!! LOL and gave him some tips.
When I was next I just told the range guy I was going to wait until he finish no way I was going to be near him with a loaded gun.

Could be. He took a pretty good but justified beating and may be embarrassed to come back and post. What makes me suspicious is his claim to own other S&W semi autos, including a "suppressed .22?" . If he's a troll, he went to a fair amount of trouble. If he owns other firearms as he claims, then he's never had decent instruction in their use.

An astute firearms instructor recently told a class that the ammo manufacturers never intended their ammunition to be chambered more than one time.

Just a note on hand-cycling live ammo...
Of course, as everyone agrees, it's VERY dangerous.
As a general rule (exceptions apply), much of the less expensive "range" or "target" handgun ammo is NOT crimped heavily so bullet setback is an immediate concern and the brass is sometimes softer and less "springy" so the case rims and brass quickly become distorted and chewed up.

On the other hand, most premium self-defense and duty ammo IS crimped more heavily and has higher quality "springier" brass, which factors resist the damage done by hand-cycling to some minor degree.

Experienced shooters know full well the risks associated with hand-cycling ammo, as has been repeatedly stated in this thread. The use of high quality snap caps is worth the cost.

"Can you guys help or should I just bring it to the shop I bought it from and have their blacksmith look at it." uhhhhh......fyi, it's "GUNSMITH."

Sorry if this sounds rude, but much of the evidence you have left here leaves me to say don't shoot until you "GET FORMAL TRAINING", learn the proper terms, don't think you know more than the next guy. Lot's of safe, informed and experienced info on this forum.....PLEASE....??

Where did I say BLACKSMITH and if you don't know the difference between a gun safety course and FORMAL TRAINING take the courses and you will see what I mean.

Troll or not, I've found the thread most entertaining!

Double Tap...Sorry

You didnt.

He utilized your quote to start off showing how bad a situation this is.

Then he posted the OP's original wording IE:Blacksmith, in some quotations " " to reiterate how bad a situation this is.

Then went on to build on your thought by providing his thoughts aimed at the OP and how bad a situation this is.

It was all one constant train of thought at the OP

Thank you for clearing this up.

I hope the OP will find a blacksmith with a 9mm anvil. My experience with them trying to use the 40 cal on my 9mm has been very disappointing!

I want a 9 round mag for my Shield 9. But from the OP, it sounds like they're ****.

I tried using the 45 round factory magazine from my Shield 45 in my Shield 9 but it wouldn't fit.

Well there's your problem right there. Its a 9 round CLIP man! the 9 round mags are ******. Ya gotta use a 9 round CLIP. But it sounds like the clips are not much better.

Ive heard those 9 round clips cause all kinds of malfunctions and general problems....which brings us to why we are here

Personally Im gonna stick with the 7&8's

I carry with the 7 and keep the largest one I've found in a custom IWB holster.

I don't think this guy is a troll.
Over the past few years, lots of people have been buying guns and proceeding without any kind of formal training....yeah, scary for sure.
I've seen it at the range many times. One instance was so bad, I packed up my stuff and left before she accidentally shot me!!
I think this fellow may be one of those. I know everyone meant well in their advice and I hope he heeds all the good stuff.
Should he come back on here and read this: Get some formal training - it's not something to be embarrassed over. Trash that ammo that you've been cycling thru that gun...its worthless. Clean/lube the gun again per the manual, get some good brass ammo and go shoot the darn thing AFTER you've gotten some good instruction on safety, proper terms, use, etc.

I agree with you, to a point. As experienced shooters (which lots of us are), you almost have a duty to go to someone who is behaving badly or seems new, confused and dangerous (not maliciously so) and HELP them and teach them...at least to be safe.

I'm an NRA trained RSO, but at many ranges I've shot outdoors, everyone assumes the role of RSO by being there. If you see unsafe behavior, you owe the person (and the other people around you) enforcement of the basic rules of safety. You all know what they are, help others understand and stay safe.
