Lately at the range I've run into quite a few people who are using FMJ's for their carry/defense weapons...I guess price and availability of some stuff can be a factor here...aside from over penetration,I guess it's just as effective as anything else and a lot cheaper as well...I do this in my 380 LCP,but all my other carry/defense weapons have JHP's as a rule...Any thoughts on this ? I'm sure I can stand to learn something here...
