    Hi there. Just bought an M&P40 (Full) last week. I shot 100 rounds next day of purchase. They were FIOCCHI FMJ 180 GR and the gun shot perfect with no feeding problems. Next day I shot 100 more rounds with FIOCCHI FMJ 170 GR TRUNCATED and 2 missfeed occured. :fire:
    Just wanna know if some of you guys had problems with these ammo or could be a "lemon" m&p.

    Will appretiate all your comments about this issue..

    It's the ammo; sensitivity to bullet profile is a known trait of the M&P 40S&W. The good news is that it's not any of the SD ammo that causes it issue, but specifically target ammo in a broad meplat'ed truncated cone (TC) configuration.
