First round fired from my new Glock 20 Gen5 10mm. This trip to the range with a new Glock was somewhat discouraging as it intermittently failed to feed Fiocchi 180 grain FMJ-TC. On its second day at the range, it cycled flawlessly with Blazer Brass and Winchester 180 grain FMJ. I burned through what remained of the 200-round box of Fiocchi ammo in subsequent trips to the range and it routinely failed to feed.
