I went out and fired my S&W 9 MM Shield pistol. This is what happened: I shot approximately 80 rounds though the weapon. During the 80 rounds I fired the weapon it ejected the spent cartridge and reloaded the next round ok. But the weapon did not cock the striker. I had to eject the bullet that was in the chamber and load another shell in order to get the weapon to fire. What would keep this weapon from cocking the striker since it ejected the shell and loaded the next bullet properly?

What kind of ammo were you using?

what makes you think it didn't cock the striker, if you loaded another round and it fired, maybe you had a hard primer or the slide wasn't fully into battery...

I'm having the same issue with my 9mm Shield.. Been out twice with it and have fired at about 250 rounds thru it. Using Federal Champion 115 grain.. First time out I had 2 FTE and 2 FTF out of 175 rounds. The second time out I had 2 FTF..I checked the bullet and the primer cap wasn't struck.. Not very impressed with this gun in spite of all the reviews.. Going out again this weekend and see how it does.. Maybe in the market for another Glock if the Smith doesn't live up to my expectations..

sounds like it could be limpwristing. i have over 2000 rds through my shield 9 and 40 not one hiccup and i fired maybe 100rds factory and rest are my own reloads.

Send it back to S&W

A sd firearm must work every time.

Yours doesn't.

Hard to have confidence in a pistol that lacks the fundamental quality of reliability.

Just my opinion, of course.

Was it cleaned and lubed as per the manual before you shot it?

Please spell out the malfunctions. Are you talking about Fail to Fire or Fail to Feed? Is it Fail to Eject or Fail to Extract?

The OP's problem cannot be limp wristing. The slide doesn't even need to move far enough to eject a shell to cock the striker.

The problem is fail to fire.. also had one fail to eject the first 100 rounds or so, but none since.. only fail to fire

450 rds through my new Shield 9 and not one gun related issue. Breaking in very nicely. Now, if SW would ship the extra mags I ordered over a month ago, range days would be even more fun.

I used Winchester ammunition. The weapon was properly cleaned and oiled according to the instructions in the booklet. I would have answered sooner but I was waiting on an e-mail telling me that some one had answered. I did not receive any e-mail.

Jack, I know for a fact it did not cock the striker. I pulled the trigger back as far as it would go two or three time and it would not fire. It was not cocked.

What you had was a failure to reset
Thought the Shield set up was supposed to have corrected this problem that had occurred on MPs in the past
I had the same thing happen once in 250 rds on my new MP9C with the new Shield trigger reset
Since then I had the Apex FSS installed

Wayne,
Sorry about the problem. Sounds like mine from last yr.(ser# HAW54xx). Sent it back 3x. They replaced the striker twice and then finally the slide and barrel and voila! Problem gone. It was mostly with W-W ammo too and they(S&W) said in the "rush to market" that primers were getting through that were harder and more resistant to firing. Well...that`s all good and well but if the ammo is state of the art it should fire everything...and it does now that they replaced the barrel and slide.

Good Luck, John

Tim, it failed to fire. It ejected the spent cartridge and reloaded a live round but did not cock the striker. This is very obvious as you could pull the trigger back as far as it would go and it was not cocked. I know this seems strange but this is what happened. I see where this happened to another person above too. I may have to call S&W about this and see what they say. This is a brand new gun that I had never fired before.

Much Ado, I am glad to have found some one who has experienced this problem before. It is a little difficult to try and explain. Thanks for coming to my rescue. Unless some one can come up with a solution I feel I may have to send my weapon back too.

I am glad that some one has had the same problem I am having. I may have to send it back for repair. I can never trust it as it is now. Thanks for all the replies.
I wonder why I am not getting e-mails telling me when an answer to my post are made.

Does the sear move freely? Perhaps something is seizing it?
Does your striker assembly wiggle at all and have you removed it to inspect it?

See if there is any damage to the white plastic part.

Wayne,
Here`s the deal...you will have to send it back. They will not send a new striker unless you`re an armorer. And mine was hitting the primer, just not enough.

You need to get 5 or 6 hundred rounds down it before you make an assumption. Break the weapon in first. Is this a reoccurring problem, or has it only happened the one time? It may only take a few more rounds down the pipe to know all is good. Kind of sounds like it short stroked, or it light struck the primer. It would be nearly impossible to feed the next round and not cock the firing pin. Maybe the pin followed the slide, but unlikely. I would see if you have any more problems before sending it in for warranty. Gun is still on the tight side.

I repeat it is a failure to reset
There were problems in the past on MP9s
Called sear flutter that sometimes resulted in a failed trigger
Forget this light primer stuff
The gun didn't reset
The Shield had a new RAM it was supposedly immune from this problem so S&W early in 2013 used it on all their MP9s
Evidently it can still happen as it happened on my new MP9C after about 200 rds next 50 were OK
Since then I had an APEX FSS installed ( because I didn't like all the pre travel etc )
No problems 110 rds but we shall see

I had the same problem, but I called it trigger failing to reset. It went back to the factory twice, but after changing everything but the slide and the frame, it now runs fine. Mine was a Jan '14 production.

Gun was **** to start with, but the CS guy (same one both calls) really worked for me. He had the gun sent to him after the last repair and tested it himself (and sent it back again).

All else aside, their CS rocks (as the kids say).

Wayne937 has it right guys. He knows what he's talking about.

This isn't make believe.

He has to send it to S&W

No amount of shooting will fix this.

The problem is not new to the Shield or MPs.

I know many folks have these pistols and have never had a problem with them. That's great.

They are too buggy for my taste as an sd option. I have no confidence in them.

The pistol is of no use if it won't work every time.

Just my opinion, of course.

If it proves not to be the ammo or bad technique, it's defective. Send it back to S&W and ask them to fix it. New guns get quicker turnaround.

Thanks everyone for your suggestions. I sincerely feel that this weapon needs sent back to S&W for an inspection. I will not be able to trust it if I don't send it back. For my piece of mind, I will be calling S&W soon.

How can it be adequately tested
Mine failure to reset didn't happen till the 200 rd
None on the next 160
How many did he fire
Unless S&W knows what the exact problem this sending it back and they change parts around is just a hit and miss deal
Three people here have had the same problem --fail to reset
Just wish S&W knew exactly what causes the problem

Terrible advice. Spend $180 in ammo to prove a problem exists? This is not a 1911 gun forum where break-in is typical. Striker fired guns should work out of the box without compromise.

All pistols should work right out of the box. Otherwise they are broken or defective.

Over 2,700 rounds thru my Shield 9mm (Documented + or -) a Mag or two. Not one single malfunction, Its accurate and very reliable purchased about 8/2012 so it was an early release gun. Plan on buying another Shield 9mm next week.
10-8 Rear Square Notch and the Ameriglo front sight. Great little gun IMHO

1SG
Out

Mine is doing the same thing.I bought mine nib two week's ago. Went to the range and fired about 125 rds. and it did this about 3 or 4 times. Went today and fired 100 rds. and it did it about 3 or 4 times again.

Well that is 4 people on this forum and I doubt every S&W Shield owner is here so S&W has a definite problem or I should say the owners do
I just hope having the APEX Trigger FSS installed on my MP9C fixed the problem
110 rds so far

For anyone that wants to test this theory.

I was watching Apex Tactical Videos, tonight. At the end of this video (@ 8:00) makes me think that the loops that activates the sear may not be adjusted properly on the failing Shields. just a thought.

Good catch. You're probably right.

Glock has had issue's to from time to time.
just saying.

Even if your gun functions correctly why should anyone have to install and aftermarket APEX trigger to make it work (which probably cost around $100)...would you buy a car/truck and then be told you would have to spend $1000 more bucks to make reliable for you wife to take your kids to school...just saying...other brands of polymer work well out of the box...like GLOCK....

I had it installed because it makes it close to a 1911
but I am hoping the failure to reset goes away in the process

Yes I agree you should not have to go after market to fix a manufaturers problem

Smith and Wesson Tech support told me the factory puts a very heavy coating on the barrel to protect against rust. They said it will take about 3 good cleanings to get that all off and the gun may not go fully into battery until that is completely cleaned. Said after the third cleaning and oil it should work perfectly

Well if this is true, does not reset, I am going to hold off and wait until Glock comes out with a 9mm slim line and then buy that.

Get comfortable.

You don't have to install these to make it work properly. The point of it is for personal preference. The point of the video being posted is for the information at the end of it. The trigger on these pistols, unlike many, are very adjustable. The trigger bar loop, if not set right, at the factory can cause a malfunction.

Before that is attacked, a naturally aspirated car can handle a ton of variables. Put a turbo on it and a ton can go wrong if one thing is out of whack. Most guns are made to work how they work. This one had adjustability.

If you are not sure what is going on with your firearm, by all means, send it in. But, I think of a pistol like a car. If I am going to own it and trust it with my life, I need to understand how it works and be able to a fix it myself, to the best of my abilities.

Yes Glocks are reliable, But that is because they are not made with adjustability. Sure you can buy parts that make the trigger pull different or polish parts. But, a 100ths of and inch of an adjustment to the trigger bar can turn a stock trigger into a dream trigger for a M&P user.

My new purchase last week did the same failure to reset. CS agreed it happens infrequently.

WEll as I posted my Fail to reset happened after 200 rds
Next 50 were ok
Had the Apex FSS installed and 225 rds since no problem
