.So if all handgun calibers are concidered weak and not that effective in stopping the bad guy why do we (self included) spend the extra money on high performance ammo? Seems we may be better off buying the more inexpnensinve types of ammo (FMJ) and getting more time behind the gun?
FMJ isn't designed to expand and has a high risk of zipping right through a target, possibly causing collateral damage to whatever is on the other side. Hollowpoint ammo is designed to expand, both causing greater target damage and preventing excessive penetration.
Practicing with FMJ range ammo is certainly fine and encouraged. Heck I use my own lead bullet reloads. I guarantee you though I'm going to want a +P hollowpoint if God forbid I ever have to use my handgun.
