THANKS to this forum

just want to say THANKS for all the info here it's very useful, I recently ( june) bought a 9mm shield, even knowing I might encounter issues, well lo & behold I had ejection issues 1 maybe 2 out of 100 rounds of Winchester white box ( red lettering) so tried 2 more 100 boxes thinking it might be a bad batch or something, same thing, so after reading about trying different ammo I bought 100 rounds of Remington, 2 more failures to eject, now we're up to about 6 total failures so with out getting excited I bought 100 rounds of Federal 115 grain & 100 rounds of Winchester NATO 124 grain haven't tried those yet but the Federal went thru flawlessly NO failures so I think I found the right stuff ?, I'm left believing these shields are finicky on what you feed them, maybe not all but some, so THANK YOU forum friends for your info

Or it could be that the gun is just now getting "broken in". You might be surprised if you now try the ammo you had problems with originally. Like most machines, pistols are a bit stiff in the beginning.

Bkreutz is right. All the moving parts have to fit themselves. It is kind of like buying a new pair of running shoes. You would not buy a new pair of running shoes and then run a marathon would you. No, you would first break them in by taking small runs near you.
Just bought a new M&P AR VTECH II. Took it shooting for the first time Friday night and again yesterday. The more I shoot it the better it shoots. Right now she has between 200-300 rounds through her (maybe closer to 300) and she is running flawlessly. You could tell when the parts started fitting together, the groups just got smaller and smaller. I can safely say that the gopher on the life sized gopher target at 50 yards is totally dead.
