I am not, nor claim to be, an expert on this, but I do like to think of myself as a "student" of this event, among others.

I think you really need to go back and research the events, etc., surrounding the "Miami shootout".

I think you will find the failure was NOT of ammunition, but of tactics.

At least that is how I see it.

As to the OP, you certainly can carry what you please, but I would NOT be carrying FMJ, in anything other then a .380 (or smaller), for a concealed carry handgun.

Just my honest opinion.
