Don't know about Fiocchi in .45, but my wife bought some for her Kahr .380 and while it ran well it was really dirty. My wife had GSR speckled all over her face and arms after a trip to the range. We won't buy it again. I shoot Atlanta Arms ammo in all my STI 1911s and 2011s and it is excellent. Was turned on to it by the guys at STI who use it for their testing. I buy the remanufactured for the range and their new for competition. AA also makes match grade if you are a serious competition shooter.
