I bought both a PC 9mm and a PC .40 cal. Have had no issues with the 9mm but had to send the .40 back to S&W with my notes on failures to feed. S&W cleaned up the ramp and tweaked some other things and I have had no FTF issues since.

I also live out in the country and have fired the PCs at night just to test the flash for myself. I could not tell a difference firing a regular shield and a PC shield at night with respect to flash.

Also if I have to ever use my carry PC shield in close quarters I believe that any flash burns will be soon forgotten if I live through the battle.
