Thanks for the replies.
Sorry I can't be more thorough but it's not my gun. As I stated, it belongs to a friend and he lives one state east of where I am.
I do have the brass so I can say with certainty that it's the right size ammo. The cases are .380 auto. That gun only comes in .32 and .380 and I'm pretty sure the slide wouldn't close at all if he was trying to put .380 ammo in a .32 gun
It wouldn't surprise me if he hadn't cleaned the gun before trying it out though...
