I've had one of each of the black in color Hellcats. I have carried a Hellcat PRO for over 1.5 years now. I prefer it over the other Hellcats and all other CC handguns.
I practice support hand draw, support hand only mag changes as well as support hand only malfunction drills. I also practice shooting with my non dominant eye. The first time you attempt these drills shouldn't be the moment they are needed.
