So this is the one I figured would elicit the most opinions. I've owned or fired .357s, .44 Mags, .45 longs. I've had a Security 6 and a Super Blackhawk, both fit and both were comfy. Neither were a problem to shoot. But I'm open to any brand or caliber. I'm ambidextrous, should I consider two? Does the .45 long have an advantage over the .44? Ammo for the .45 seems rough to find. What say you, pardners?
