Shield recall

Email just received from Meltzer's Sporting Goods, my local store.


Reports of distributors and dealers being told to halt sales of Smith & Wesson M&P Shield pistols are flying all over the Internet, leading many to believe a recall is pending.
Fortunately, it appears the problem could be limited. Smith & Wesson has posted a “safety alert” regarding a specific malfunction of the concealed-carry pistols’ triggers.
That being said, the flaw could affect any M&P Shield manufactured prior to Aug. 19, 2013, so it may be present on essentially every Shield ever made currently on the market.
“We believe this condition is largely limited to recently manufactured M&P Shield pistols. However, out of an abundance of caution, we are asking all consumers of all M&P Shields manufactured before Aug. 19, 2013 to immediately inspect their pistols for this condition.”
What’s happening is that in some cases, the pistols’ passive trigger safety is failing to engage even if there is nothing putting pressure on the trigger. Normally the safety would prevent the trigger from getting pulled except when it’s being handled.
In addition, pistols with a stuck trigger safety are not drop-safe.
“Smith & Wesson has identified a condition where the trigger bar pin could damage the lower trigger in certain M&P Shields in a way that may affect the functionality of the drop safety feature of the firearm, potentially allowing the pistol to discharge if it is dropped” explains the Smith & Wesson safety alert.
“Any unintended discharge of a firearm has the potential to cause injury, and we ask that you STOP USING YOUR PISTOL IMMEDIATELY UNTIL IT HAS BEEN INSPECTED AND, IF THE CONDITION IS FOUND, REPAIRED.”
If you have a Shield with this problem, you’re advised to send it back to Smith & Wesson for service. If you’re uncomfortable with performing the inspection procedure Smith & Wesson is asking that you take your Shield pistol to a local M&P certified armorer for inspection.
***MELTZER'S IS NOT A CERTIFIED ARMORER, sorry***
While the pistol does have a manual safety, the passive trigger safety has a long track record for reliability and safety, and is faster and easier to use in a stressful situation. Because of this, many people opt not to use it. For those people, the Shield effectively has no safety to speak of.
Of course, if you do have this issue with your M&P Shield, Smith & Wesson will repair it for you at no cost including shipping. They are expecting a five- to seven-day turnaround on all service.

The M&P Shield has been one of Smith & Wesson’s biggest sellers ever since they announced it. A slim, comfortable pistol designed for concealed-carry and backup use, the Shield has quickly risen to the top in terms of popularity, in part because they also have a great reputation for reliability.
These guns have sold extremely well and are at peak demand as concealed-carry becomes more and more common across the nation.
While this flaw does not affect their reliability in any way, it’s definitely a good idea to check your Shield’s trigger for your own safety and the safety of others.
 
My only question is if you owned a Shield that was flawed by this safety issue and you didn't subscribe to this forum, would S&W notify you, "or"....?
Yeah... I did an Online registration for mine and haven't gotten an email from them (yet). It would be nice if they did use your registered email address for more than just sending new product ads. ;)

I actually heard about this on another forum before it was posted here, but as we all know... It was mislabeled as a possible recall, rather than a safety notice.

I'm actually surprised that the OP (or one of the Moderators) hasn't changed the Thread Title to "Shield Safety Notice".
Sure would be nice (hint, hint). :)
 
The guy u spoke to can't read (he must own a Springfield, cough cough). It would be hard for me to take advice from him. :)

It clearly says SAFETY ALERT.
The cough you have is more psychosomatic rather than an actual related to fact. The XD's are excellent handguns, as well as the M&P's... even w/Safety Alert ;)
 
I see no reason to send mine in. I can manually move it out to where its supposed to be.

That's interesting, I have two shields bought this year, one with a May date and one with a July date. The July build, the pin for the trigger hinge appears to be set too deep on the trigger which then protrudes on the right side of the trigger enough to be felt. The May build is flush on both sites. Both triggers function fine, but the July build pin looks like the one in picture 2 on the link in post#17 and the May build looks like the one in picture 3. Here's the link for those that don't want to go back to the post: S&W Shield missing a spring? - M4Carbine.net Forums

NOW we're getting somewhere. Thanks for the link. BTW, my 40 Shield is just fine. And I especially love my trigger mod (search my posts and see my report on that).
 
Not so. An object in free fall due to the acceleration of gravity will never exceed 1g. G forces must be generated by an outside force in addition to gravity.

The math based on Motomed's assumption that the trigger assy weights 100 grams and a trigger pull of 5.5 lbs would be:
100 g = .1Kg
5.5 lbs = 24.465 N
acceleration required = (24.465N=.1Kg x a)
therefore a=244.65 M/sec sq
g's = 244.65 / 9.8 = 25 g's

You would have to drop or throw down your piston at 25 times the acceleration due to gravity to overcome the trigger pull required force.

Rastof is confusing velocity with force. And even if velocity were the relevant variable, you'd have to drop if off the top of a building or something for the fall to take longer than a second and reach a velocity greater than 9.8m/s
 
I think we need to hit the pause button.

The isolated faulty Shield trigger is like owning a very reliable truck with a bad radio.

I am not about to sell the reliable truck when the radio doesn't work nor am I going to switch brands based on the radio alone.

I'm glad you put it that way. For the life of me ive been trying to figure out how to explain it without causing confusing to the already confused people.

You hit the nail on the head with this one.
 
I got my Shield 40 today at a gun show for $389. The first one that I looked at had the trigger problem so i asked to look at another one and it was ok.
 
My Shield was from the first run of guns in spring 2012. It seems to be just fine. :)

No, I've confused nothing. Velocity is a function of force. Or is Sir Issac Newton wrong and force doesn't equal mass times acceleration?

An object in free fall...
Yes, but we're not talking about free fall, are we? Remember, it's not the fall that kills, but the sudden stop at the end.

The math involved in this is not simple. In order to calculate the actual forces involved you have to include not only acceleration and mass, but time and distance. Not just time distance traveled, but the time and distance it takes to stop.

I'll choose to believe the engineers at S&W. If what you're saying were true, why spend the money to make the articulated trigger? Even more so, why take the time and effort to put out this safety bulletin? They could save a bunch of money by just doing nothing.
 
After the first page or two of replies I gave up reading most of them. So ...... I apologize if the information I am linking to here has already been posted by someone else.

This is from the S&W website where I queried "Shield Trigger Alert". It directed me to a "IMPORTANT CONSUMER SAFETY ALERT" and the following PDF file:
http://www.smith-wesson.com/wcsstore/SmWesson2/upload/other/M&P Shield Safety Notice (PR).pdf

As this post is buried deeply into 5 pages or more of replies, I think I will start a new thread highlighting this file.

Just curious if anyone has actually diagnosed the problem that causes the lower trigger assembly to fail the test.

Is the hinged trigger binding somewhere? Is it missing a spring?

I believe the full size trigger uses a plastic tab molded into the trigger to act as a spring, but does not use an actual metal spring on the lower trigger assembly. Is the shield trigger different from the full size?

Motomed already pointed out that from the typical drop heights, there is very little time for the pistol to accelerate to any substantial velocity.

Motomed already pointed out that the time required for the trigger to travel to its break over point is time that the force is spread over requiring more impact force to fire it.

I agree. It's not designed this way for nothing, but everything Motomed has posted is correct.

I'd like to see the design study behind this feature and see it tested like Myth busters would do.

Did you read the info S&W postes on their site? There are at least three links to it in this thread.

Yes, but S&W doesn't give a detailed explanation of the actual cause of the problem...."Smith & Wesson has identified a condition where the trigger bar pin could damage the lower trigger...."

Wondering if anyone has taken apart the trigger assembly to diagnose the actual cause of the defect.
 
I just checked my M&P .40 Shield and the the trigger is good. The lower trigger part and tab reset as they should. My M&P .40 Shield was purchased 02/01/13 and test fire date was 01/23/13.
 
HMMM,
Before all the "new" Mass, NY and CA compliant guns came out, this is the way most guns worked. If you dropped it there was a chance of an AD.
 
Shield Recall

A good friend of mine who is a firearms instructor sent me this link Friday night. He knows that I have several S&W, M&Ps, and that for several months was carrying my Shield 9mm for an every day duty weapon. I still do a fair amount of shooting with it even though I carry it only off duty now.
The Link:

M&P Shield Safety Alert - Smith & Wesson

Instructions are clear and easy to follow. I am happy to report that my Shield 9mm is OK. I performed the test several times and it was fine.

I hope you all fair as well! Above all; "Be safe out there"

Good Luck!!!
