Ruger or S&W .44 mags are pretty much the "standard" carry gun up here. Lots of .460's, 500's, .454's etc also, but I haven't met very many people yet who actually practice with those big cannons. At $2-$4 a shot, its simply too expensive for most people. The .500 in particular is a expensive beast to feed. They are fun to shoot though.
One warning on the 329. They recoil back fast enough that many of the heavy loads will jump crimp and lock up the gun. My brother carries one, but can't use anything stronger than HSM 300 gr loads. The 320's or the +P 300's will cause problems in his gun. He's also had a couple issues with the recoil tearing up internal parts, and it's been back to the factory once for a rebuild.
I mostly carry a Glock 10mm now. Not because I think it's better, but because I can just flat shoot it faster and more accurately than I can my .44's. The extra capacity is a bonus that that doesn't hurt. Sure I might not get more than a couple shots of if a bear charges me..... but its 50/50 odds that it will be chewing on my partner instead, and I want all the rounds I can get in that scenario.
The Ruger .44's aren't getting sold though. I like them too.
