(1 out of 5) Does not run in S&W 5.7
by Zeb from Columbus, OH on January 12, 2026

As the title states. Bought 6 boxes of this on sale. Can’t get a single magazine to run through. Other ammo works, this has not for me.

(5 out of 5) Second opinion on compatibility
by Dale from Reynoldsburg, OH on February 11, 2026

Not to argue with a previous review, but I had a different experience with this ammo. Using a S&W M&P 5.7 and a Panzer AR57 upper on an Aero Precision lower, I ran through 144 rounds (2x50 from the AR57, 44 from the S&W) at Vance Obetz indoor rifle range without an issue. Perhaps the previous reviewer had a bad lot of the Fiocchi ammo.
