[QUOTE="MattyD.]Honestly, with all of the advances in modern self defense ammo, the big 3 favorite calibers are so close to each other now that it shouldn't matter. Shoot what you like and have peace of mind about it.

I belive you hit the nail on the head, one of the key items when practicing defensive shooting in my mind is to occasionally fire your carry ammunition and feel comfortable with it, make sure things are cycling like they should and if not hey its only training now is the time to correct it. It would be a bad deal if all one practiced with was FMJ range ammo that worked great at the range regardless of caliber but with no self confidence in your carry ammo it's kinda like leaving it up to faith imho
