I thought that a 380 auto and a 380 acp were the same round. It's different enough that in my S&W Bodyguard 380, the TulAmmo 380 acp would not fully chamber the round. What a bummer to be on the range, at the firing line, ready to pull the boom switch and you realize, it's not going to work...
I wonder if this is a Bodyguard issue or a TulAmmo issue? Everything that i can find on the ole interwebs seems to indicate that 380 auto is just an abbreviation for 380 acp.
I realize that many folks won't shoot non-brass cartridges or 380s, that's not the what I'm interested in hearing about.
