hi Sat, welcome! The Kahr .380s are awesome guns! I also run Underwood but go for the Extreme Defender, which delivers a little more penetration than mushrooming JHP rounds but I sometimes carry a 2nd/ 3rd mag of JHP.. and also usually another gun of larger caliber, as 'back up'..as well as a knife in pocket and a longer barrel 'primary weapon' in my car, with several hundred rounds of each bullet I'm carrying.. because you never know when the zombies are coming, you just that they are.
;D
