Shield recall

Two Shield 9mm's bought seperately. Neither seems to have the problem mentioned in the "safety alert". However there is a little difference in the two when doing the check that S&W recommends. The one that I shoot, the little tab behind the trigger at the top, you can see more than on the one that has never been fired since it was purchased. It does look the same if I push slightly forward on the bottom of the trigger. The tab does appear on both guns after pulling back on trigger and releasing. Could this be from gun never been fired and needing some break-in? Curious as to what some might say. Thanks.

Friends, John

Thats what I am wondering. New stuff can be stiff.

Anyone else's malfunction and you plan not to send it in?

So really its nothing to worry about. I won't be sending mine in at all.

I was going to give up, but this phrase concerns me. Someone not getting their malfunctioning gun fixed concerns me because it could be dangerous. So, I talked to a real engineer.

I work in the aerospace industry. I calibrate accelerometers for a living. Because of my experience, I knew instinctively that a simple drop of an M&P could generate more than 25g's. Alas, I'm not well versed in the actual math. So, I spoke to a friend who is well versed with this stuff. He is a system designer for data collection systems on test aircraft. Here is his response to my question:

The basic problem is simple in theory, but likely difficult to make the assumptions required. You need to first determine the velocity at impact (easy), then determine how long (correlating to how far) it takes to slow down, sounds simple at least.

Using the conservation of energy equation: 1/2*m*v^2 = m*g*h, you can find the speed at impact (5.425 m/s), but then you need to be able to determine deceleration at impact, which is what your looking for. This would be based on what material it landed on and how much energy went into rotational velocity (how much the gun spins after impact). Landing on a pillow would be far fewer g's than concrete after all.

Assuming no energy is converted to rotation (meaning it landed flat, and bounced up flat), and assuming constant deceleration, and assuming the total deformation (summing the ground material deformation, and the gun's deformation) was 1mm during the impact, you could find the deceleration rate:

a = (Vf^2 - Vi^2) / (2 * S)

where Vf is final velocity (0 in this case)
and Vi is the initial velocity (5.425 here)
and S is the distance traveled (1mm here)

a = -14715 m/s^2 or -1500 G's (assuming 9.81m/s^2 for 1g)

He wrote a bunch more about elasticity and deformation, but it only adds to what I've posted above.

The affects we're talking about here are significantly higher than the 25g's some were concerned about. As you can see, just a simple drop generated 1,500g's and that didn't destroy the gun. The numbers would be much higher if the gun was impacted with more force, which wouldn't be hard to generate. Thrown down or dropped from a higher distance would do that.

This is what I've been getting at all along. The engineers at S&W have worked all this out through processes like I posted above and with more detail I'm sure. They wouldn't have put the safety there, considering the cost, if they didn't feel it was necessary. More, they wouldn't have put the Safety Alert out if they didn't feel this was a significant problem considering it will cost S&W plenty to fix them.

Whether or not a person decides to send their gun in for repair is a personal choice. Think hard about the ramifications should you decide not to get it fixed. The gun will only be gone for a couple of weeks. An accidental discharge could be a life changing event.

My issue is I JUST got the gun. Have not even had a chance to shoot it yet. If I send it in, I have nothing to carry. Not worth the time of not having it to me.

If ur gun is having the above problem. I'd suggest sending it in and having it fixed. Its FREE and it likely could save a life from an accidental discharge farther down the road. IMO, u would be ignorant to carry a weapon that you know is defective and posses a possible risk to you or another persons life. Thats the reason there is a Safety Alert to begin with. S&W would rather fix it than to hear a story of a customer and an accidental discharge.

Now if ur gun checks out and its working as designed. I'd say carry on, and have a nice day.

Remember guys........SAFETY always comes first.
 
Yeah... Looks like S&W isn't the ONLY company playing it safe this week.
Half the folks over on XDTALK are doing a 'Chicken Little', while others are pounding their chests with indignation over their brand new $600 pistol being 'garbage'.
(Sound familiar?) :-)
I'm just glad that companies are playing it safe, so customers don't get hurt.

Mine does not. But right now, being brand new, the time away from it does not justify sending it in.

Striker blocks can fail...or should I say FP's can overcome a SB. So if you are relying on Internet physicists on the relevancy/redundancy of the drop safety, or the striker block alone...you might want to reconsider.

I guess I just don't understand your logic here. You said you just got the gun. I get that you're excited about having it. I too hate sending things back. But, it won't be gone long.

You also state that this malfunctioning gun is the only gun you have to carry. Did you trade another gun in to get this one? If you didn't, what did you do before you got this gun?
 
I'm sitting here waiting on Kimber to recall all the UC 1911's. So far Shield and XDS. The Kimber UC cant be too far behind, lol.

Yes I did. Thats part of why I am frustrated.

Guns are mechanical, so they're subject to failure and redesign. These issues are not isolated to S&W.

LOOK at what I just got:
"Springfield Armory® is initiating this voluntary safety recall to upgrade 3.3 XD-S™ 9mm and 3.3 XD-S™ .45ACP pistols with new components, which eliminate the possibility of a potentially dangerous condition. We want to emphasize that no injuries have been reported to date.

Springfield has determined that under exceptionally rare circumstances, some 3.3 XD-S™ 9mm and .45ACP caliber pistols could experience an unintended discharge during the loading process when the slide is released, or could experience a double-fire when the trigger is pulled once. The chance of these conditions existing is exceptionally rare, but if they happen, serious injury or death could occur."
 
What happened to all the shield cool aid drinkers that were calling the OP a probable rumor starting idiot?

Out returning the XDs they bought because they thought the Shield was the only one with an issue, lol.

Although they still did not RECALL the Shield. Its amazing how many people miss that part.

They're hunkering down with the XD-S Fanboys that were laughing at the Shield Safety Alert. :D

And of course... We've all (hopefully) figured out by now that it's NOT a Recall, as the OP reported... So Part Right/Part False (for those that want to split hairs and pick knits). ;)

Edit to add... Smitty beat me to it by a few seconds.

I said it a few times, when my dealer called, he said it was a recall. I posted on here right after.
