So... This 750 rounds has been using the original "Bent/Damaged/Defective/Design-Flawed" RSA?
Sorry to hear about the occasional FTE problems. Has everyone who's shot your Shield had the same problems?
I now have well over 5K rounds through mine and looking into getting a replacement, but when I called CS, they say they have none to send/sell. Oh well.
Yeah, I'm amazed that it has performed so well with the Factory-Crumpled RSA Option. In a perverse sort of way, it's a tribute to S&W's engineering. I'm really looking forward to seeing how it runs with a straight one.
I know that FTFs and FTEs can be caused by a variety of things other than dinged-up RSAs. I suppose I could have limp-wristed the Shield, but I've had only two FTEs in over 6000 rounds with my SIG P250, SIG P320, and M&P 40c combined, so that's not normally a problem for me. Then, there's my old Ruger Standard... but I digress.
It might be ammo-related. Most of the failures occurred with Win NATO 124 or AE 147, which comprise the bulk of my 9mm target ammo horde. I have 100 rounds of Win 115 that I have yet to try, but I prefer to practice with a heavier weight bullet, as my self-defense rounds are 124s and 147s. A friend did fire one full magazine with no problem, but with a 1% FTF/FTE rate, he had probability on his side.
Here's hoping S&W will have some new RSAs for us soon.
