Red - 44 Mag.
I see you're in Denver. Not sure if hunting is in your plans, but a 41 mag is the minimum legal cartridge for hunting deer, elk, mtn lion, or bear in CO. Should you down an animal and need a second shot to dispatch it, CDOW requires even a dispatching shot, be made with a legal hunting caliber. Obviously 41's are available, but I wouldn't hold my breath walking into a small shop in the mtns expecting to find 41 mag ammo should you need it.
When I'm in the field, frankly bear doesn't bother me nearly as much as mtn lion, which can sneak up on you without your knowledge. Just this past fall, a couple walking around Newcastle (Just West of Glenwood Springs) had to shoot a mtn lion to defend themselves. I'm no expert, but in my opinion, if you really had an incident with wildlife, I don't think the critters are going to wait for your 7th shot or beyond that an auto may afford. I sure wouldn't want to deal with anything wounded, and again, my personal preference, would be a minimum of 44 mag. ( Also min barrel length is 4" ) So frankly a 629 mtn gun fits the bill nicely.
Regards,
