Don't let ANYONE tell you the .380 is not enough gun. A guy was walking in a field one day when a Wild Boar charged him, all he was carrying was a .380. He shot the boar once and it went down, then he walked over and finished it with a second shot.
True Story! Now a wild boar has MUCH tougher hide than any bad guy. Also a guy woke up one night hearing someone breaking in. He went to see and shot the bad guy once in center mass, bad guy died, he was using a .380.
The human body does not like ANY projectile entering it.
I carry a Bersa Thunder .380 IWB and trust it completely.
