I'd love to get two new mags. I have two of the six and two of the seven rounders on backorder with Cabelas, but have no idea when they will ship

They should at least own up to the problem and notify all 40 cal owners!
Is there anyone other than S&W making mags for this gun yet?

Is it possible that you can find a set of calipers and measure the mags and see if there is a difference in width between the new ones and the ones that dropped out all of the time?

Are you kidding us? If they don't send you a return label, then call them and get a RMA and mail it yourself. Holy cow.
Its no wonder no one wants to develop and sell a new product. All anyone wants to do is make the lawyers rich.
If you have such an issue, put a fair price on it with a statement about the mag issue on the board and sell it to someone that has the ability to deal without having lawyers involved.
See the pictures I posted earlier in this thread. The "new" mags they sent me appear to have been modified by hand by S&W. Don't need calipers, you can see the difference.

I appreciate your pictures. However, the reason that I asked if it was possible to measure the mags was to ascertain whether there was a different dimension between magazines that were issued with the DXP and DXT vs. later ones.
If they are altering the magazines, that would suggest a dimensional change in the magazine over the manufacturing run of the different serial number series.
If they were or are replacing magazine catch, that would suggest either a dimensional or material change in it.
I think that you're making some assumptions that may not be valid. We don't know if the mag drop problem is limited to new guns. The gun has been in production for only a few months, so there is no reason to believe that the process or the specs have changed.
The "old" mags that came with my gun were dropping and I assume that the "new" mags would drop if not modified by S&W, so that suggests that the unmodified dimensions of both sets of mags are inadequate. S&W sent me a replacement mag catch that I installed. It did not fix the problem, so I assume that its dimensions are the same as my old mag catch.
Based on the data that I have, it appears that the new and old mag catches and mags are inadequate as manufactured. The only dimension change that made any difference was made by hand to the new mags that S&W sent to me.
I think that the problem is that the high pressure and snappy recoil of the .40 cal cartridge pushes this design to its limits and the difference between holding and dropping a mag is tiny and within the manufacturing design tolerances. I also suspect that S&W did not account for enough frame flex in setting the tolerances for the .40 frames and mags.
I have already modified my old mags with a center punch, so I can't compare the unmodified dimensions to the modified dimensions. I also don't have calipers. However, I do have four mags that work now, so I'm happy.
This does pose a problem for potential purchasers. There is no indication at this point that S&W has changed the design specs of the guns or mags so any.40 on the shelf could be a mag dropper. Until S&W announces that a fix has been implemented, no one will know what they are buying. If S&W announces a fix, then they will need to issue a recall, and they haven't done that.
Disappointing. Expected more from S&W. But I love my Shield as long as the mags stay in the gun.

I called S&W and got my return label, will be shipping mine off this week. Hope I have the same luck getting it fixed as the others that have gotten theirs back! This gun is too fun to shoot to have such big issues. Thanks to all that are keeping the thread updated with their repair diagnosis'!!!

Assumptions??? I asked a question based on logic. Nowhere did I say that I think or feel.
I just asked for the dimension of the magazines that dropped vs. the ones that don't. Mine doesn't drop, some did until a magazine modification was made that increased their width at the cutout. A new magazine catch, in your situation, did not work.
Therefore (a+b=c). Are the magazines that are not dropping from factory wider than the serial numbers that are? Simple question.
Perhaps S&W switched vendors after the demand for the new weapon went off of the chart. Who knows?
But the answer about magazine width (if that comes to be the actual issue) may give future purchasers of spare magazines or those in possession of marginal magazines a tool to evaluate whether they may have a potential problem in the future.
If the magazines are straight-walled, a measurement above or below the magazine disconnect notch should be sufficient.

The only reason that I mentioned assumptions is because when S&W returned my gun and the two new mags, the note said that they replaced the mags and that the gun was within specs. The replacement mags appear to have been modified by hand after manufacture.
That suggests to be that my gun, which is SN DXVxxxx, is within specs and the problem isn't an out of spec production run on the guns. It also suggests that as of two weeks ago, the mags available to S&W needed modification to work in a gun that S&W found to be in spec. So did the mags that came with the gun two months ago.
It may be that the "bump" is the permanent fix and all new mags will have them. I may pick up a set of calipers and take some measurements. The mag walls slope inward toward the front of the mag, so it may be tough to take measurements that will be useful to others.

Turn around time ?
May I ask how long it took S&W to complete your repair?
They quoted me 10 business days plus shipping both ways.
Are they in the ball park with that estimate?
Thanks.

I shipped it with their shipping label on Aug 9th, They shipped it's return on Aug 24th, and due for delivery on Aug 28th. Now, they just came off their 2 week maintenance shut down on the 13th, so there were probably a little backed up. If you count actual working days they had it for 10 days. So their estimate is fairly accurate.

Shield .40
I purchased another Shield .40 yesterday. The last one had the mag drop problem so the gun shop took it back. I took this one straight to the range after purchasing it and shot 50 rounds. The magazines dropped out on the first shot almost everytime. This is very disappointing. I had to replace the catch on my M&P full size .40 a few months ago. That pistol is only about three years old. It works fine now, but if that was a duty carry it could be bad news. I see alot of posts on this problem but I have not seen any recall from S&W. Waiting on a reply from them now.

This is akin to a Practical Shooting match. The first two stages... can't miss. Then there's the third stage...
Sorry I gloated, but the first 200 rounds went without a hitch. But then, yesterday, without fanfare, the magazine dropped, round failed to feed, and I was fighting denial. The 7 round magazine never failed to drop after that. The 6 round mag seems ok... but I'm spooked.
The gun will go back to S&W. I'll continue to carry the 40c until it returns.
Off subject but, the Old Faithful IWB holster's kydex attachment allows carry of all my M&Ps including the 40Shield. Neat little rubber spacers adjust nicely.
