The real question may be is the 380 enough???
I carried my TCP for over 2 years... it was just the perfect carry gun... always went bang when I pulled the trigger ( mine had the stainless slide )... I did have some issues with the mag release button & spring, with corrosion as I wear it all the time, but it shot a lot of raccoons... over the years...
however I recently had to put down my lil house doggie ( a Bichon ) that was 16 years old... I laid him down, & put a FMJ bullet between his shoulder blades, angling towards his chest from 3-4 inches away... the bullet killed him instantly ( because I severed his spine ) but there was no exit wound & very little blood from the entry wound ( I know, because I placed him on his little bed in a plastic box we had gotten for this purpose ) while this may be a bit morbid for some... I chose the FMJ, over the Speer Gold Dots, because I didn't want to have to deal with blowing his head off, but I expected an exit wound with the FMJ, since he was a little dog, & there was no sign of the bullet, even though it was fired from 3-4 inches away... I often had to use 2 of the Speer Gold Dot bullets on the raccoons in the past, so my experience with the dog, has moved me away from carrying the TCP, as I no longer feel the 380 is an acceptable self defense cartridge...
so... I'm back to a J Frame... I have more confidence in the 38 Spcial, or as you mentioned, a compact 9mm... I no longer have confidence in the 380 for self defense...
