New 9mm M&P Shield - slide getting jammed back.

[85V65Sabre]

Imagine this happening in a situation where your life depends on it... you'd be DEAD!!

At least S&W isn't marketing it as a self defense pistol....................[emoji848]wait they are!!!

I have not totally given up on mine, but I'm not sure I will ever bet my life on it.[emoji17]

1st time I shot my PC Shield it was doing the same thing. Couldn't get thru a whole mag without it happening a copy of times. Went home cleaned it very very well, lubed it up and racked the slide by hand a few hundred times to break it in. Could actually feel where it would hang up at. Next trip to range lubed it up very well, including corners of the barrel and some along the barrel.
I have put 500 rounds thru her since that 1st day and she's a sweet shooter now and hasn't hung up since that 1st day.

Yes, it seems to be a barrel issue.

UPDATE!

Ok, I put 150 rounds downrange today, and the slide got stuck in the back position very often, with three brands of ammo, randomly.
Keep in mind, it is impossible to move the slide back at all. The barrel is stuck and no longer wobbly (as is normal) when the slide is back. So, a slight rap on the top of the barrel frees up the slide.

I shall clean the gun, and lubricate the outside of the barrel, maybe more than is recommended just to see if it sticks again.

Oh and by the way, you cannot reproduce this by cycling the slide manually. It only jams up when cycled with the force of an actual fired recoil.

The following is from the S&W site.
M&P(R)9 SHIELD™ | Smith & Wesson

"The reality of protection is that you never know when you’ll need it. We took the power and features of our full sized M&P pistols and put them into a slim, lightweight pistol the size of your hand. The M&P Shield is an easy to conceal pistol that offers professional grade features with simple operation and reliable performance day or night. One million Shield owners can’t be wrong."

Call S&W and return the pistol for repair.

Yep. Very disappointing. There are many high quality guns of foreign manufacture, but I purchased Smith & Wesson specifically to keep my dollars here in America. Very unreliable weapon.

I can understand the disappointment, especially when we're talking about a device made specifically to be used for self-defense. I once bought a new XDs that was a complete jamomatic until I sent it in the Springfield Armory for repair. Afterwards, it ran like a sewing machine.

There are bound to be a few issues in any product with moving parts. There have been well over 1,000,000 shields made. Most of us have found them to be reliable. It's impossible to extrapolate the numbers of them with issues from the small sample found here. It is concerning that the problem seems to appear here as often as it does.

So, this is a known issue, with a known cause and known fix. Yes, disappointing and inconvenient, but at least the manufacturer will stand behind the product and make it right.

All correct.

The points which cause the hangup are pointed out in the below pics. The inside of the slide as well as the small point on the barrel shown are too tight. This has caused the metal on the inside of the slide to mishape (the barrel also has smaller marks as shown where it is catching). The barrel we believe is a bit more hard than the slide causing the slide to show more wear. This was also demonstrated in some of our early barrels and we corrected that area of the barrel shown from the factory. Ours do not catch now.

My concern is that S&W is not up to speed with the cause or fix, and the wait time to have the pistol repaired.........

The pistol FINALLY came back 7 weeks from when I sent it in. The work order said "deburr slide". Whatever was done remedied the issue I have fired 200 rounds without incident.

Had the same issue yesterday with a new Shield w/ Night Sites jamming back every other round.

My last 2 purchases were Glocks where they say not to clean before shooting to let the lube they add work in so I didn't even think about lubing it first but when I broke it down it was bone dry on the back rails. Added some CLP and got through 150 rounds with no issue.

I have one onthe way from Bud's

I wonder what chance I have in getting a good one vs one with this problem?

Anyone have a recent sample with NO problem???

There should be a poll conducted.

If I had to guess prolly in the 0.1% range.

Yes...I have a safe full of em with no problems.

Start a thread poll if ya want!

Well, 1% is a good % I'd say. I plan to go right to the range after picking this up at my local FFL Saturday. I WILL be bringing my clean and lube supplies so I am not doing a straight-from-the box test.

I'll report back afterwards.

Saturday is a big day for me; I'm also picking up and transferring to my daughter a Bersa UL Compact 9mm, also from Bud's. This is the gun my daughter wanted over a Shield after trying her brother's SIG 239 and a rented a Shield and LC9. She did not like either one of those but strongly preferred the DA SIG. The Bersa is very similar, smaller and way less expensive than the SIG!

I'd do a poll but not sure how. The circles and graphs look pretty high-tech to me.

Do you buy a new car and take it straight to a oil change facility to have all the fluids changed?

Do a straight from box test, then clean and lube as needed, that's a real test.[emoji106]

Poor advice, IMO. There is no apt comparison from an automobile to a mass manufactured $350 gun.

I see that we don't agree on this, but I respect your opinion.[emoji106]

Well, a new car has oil in it. Sometimes new guns are dry or are supplied with the manufacturer's packing oil/grease.

I remember the very first semi auto I ever bought was a SIG 239. I was only accustomed to revolvers back then and I took it to the range right from the store. It jammed like crazy. I sent it to SIG and waited 2 weeks. When it arrived back, the service slip stated 'oiled rails" haha!! I called SIG and the person on the phone confirmed the gun was 100% dry.

I am way more aware of a gun's condition now than I was at that time (1998?) but I do not trust whatever oils are provide in a new gun.

Ever since that experience I do my own clean and lube prior to shooting but I get it that others do not and have success on their first range trip.

Hey Dad_Roman, Thanks for starting that poll!

I will be watching AND voting very soon..... My Shied is IN!

page 34 of the shield's owner manual specifically states to clean the weapon before first time use, explicitly stating to remove the factory anti-corrosion preservative.

some weapons prefer to run dry, some prefer to run wet, some don't care whether you oil them or clean them but id rather know what's in my gun before the first time i shoot it.

Your sure welcome. You guys started hinting about it and it seemed like a good idea at the time. Sometimes you put something like that together and it surprises you how long it takes

Start punchin those "like" buttons my man!...lets get that -zero- off your profile
