I was faced with the same question. For me after much opinion research reading, and some great input from SWF member ruggyh I opted for the 460XVR. It was a better choice for me as I already handloaded, and I wanted a 200 meter, totally impractical but fun precision "hand-cannon". I don't hunt so I was more looking for precision target over max energy knockdown power. With the 460 You get .45 cal bullet versatility and the capability of sick velocities! I ended up buying the 12" xvr and could not be happier with the decision over the .500 in my situation. Let me tell you this, you fire either the 460 or the 500 mag at an indoor range you better have triple hearing protection and a good pair of safety weld goggles cause in a low light situation the muzzle flash/blast is insane.. LOL
Congrats on your new X-frame. It's a lot of fun at the range and in the field. You did good to take to heart ruggyh's advice. He is actually one of the best resources of information regarding the X-frames I've found on the net. Enjoy!
The heaviest caliber gun in a remotely practical size is the model 29/629. The X-frames are novelty guns notorious for showing up in pawn shops with few rounds ever fired from them.
Sorry, but your comments couldn't be further from the truth. The .460 and .500 X-frames are very practical for their intended purposes and are the best at what they do.
They are intended to be stellar long range hunting handguns and they are. They perform well for hunting any game in North America and are popular for protection in Grizzly country. For their intended purpose, they far exceed the capabilities of the 29/629.
Saying the X-frames are novelty guns is only your opinion which certainly does not make it so. X-frames are not for everyone, but if you need the capabilities an X-frame offers or just want the high velocity, long range performance they are just the ticket.
I do not need my .460 for big game defense, but rather I know I've got a handgun that excels at taking whitetail at long range with ease. Not a novelty but one of the best tools for the job.
