I picked up my P380 a couple of days ago. Yesterday I went to the range to try it out. Shot 26 Blazer Aluminum and 25 UMC flawlessly. Shot 23 Fiocchi with several failure to chamber, failure to eject, & failure to feed. Shot 4 more Blazer flawlessly and concluded my P380 doesn't like Fiocchi. The Blazer worked great though.
