So, just to recap, after experiencing multiple FTF's due to dropped magazines under recoil, I had contacted S&W customer service (specifically M&P tech support). While on the phone, I sent them an email showing them the photo from this thread showing the old part side-by-side with the new part for reference, so there would be no confusion. They sent me the new followers, and I proceeded to "fix" their brand new magazines in order for the gun to work properly.

We've had almost daily heavy storms here, but I finally managed to pick up another 100 rd box of Federal 45 ACP and get this little pistol back out to the range over the weekend. After running nearly 100 rds thru the Shield (again) I am happy to report ZERO magazine drops. I did have one FTF which I will chalk up to possible grip issue under very warm and humid conditions, but throughout the shoot I had zero magazine drops. Also ran some hollow points to be sure, and once again zero magazine drops. So like others here, I am comfortable in reporting that (at least in my case) this appears to be a parts issue that is easily resolved by the consumer.

I wish there was something more official from S&W on this problem. I feel like this thread should be made a sticky, due to the potentially dangerous situation created by these old mags being sold for a gun that is specifically designed for self defense. That said, I can also report that S&W displayed excellent response time in my case. I would encourage everyone who buys the 45 Shield at this time to be aware of the potential for this magazine problem, as my gun was purchased in the last 30 days from Palmetto State Armory; this is a current issue that deserves the attention of the buyer. Once again, thanks to all who contributed to this thread—I am a big advocate of user group forums and you guys are the best.

On a positive note, I was reminded again this weekend of the tremendous accuracy of this firearm; every bit as accurate as my full size M&P 45, in fact several comments from our group about how it was even more accurate. Not sure about that, but the fact that I only paid around $250 for this little beast makes it an outstanding value in my opinion. Lightly went over the stippling with some fine sandpaper and overall I am very pleased with the Shield 45.
