If you want a new pistol for grizzly get the Smith& Wesson 500. Thats what I carry for the big and nasty. Easy to reload too.I am going on a horseback Mule Deer hunt in Grizzly Country. I will be with a guide. I am told that it is advisable to have a side arm for protection from the grizzly bears. The simple choice looks to be a 44 mag, with hard cast bullets, but I'm interested in hearing what you guys are using, and what advantages and disadvantages you have seen. I am limited in the weight that I can carry, so that is a consideration. I have a 6" S&W 357 Wheel gun, and hoping it is reasonable to use that for protection.
My go to is my Glock20 10mm loaded with Underwood penetrator Ammo..I have a 500 Smith in a 4". The recoil is great, and swings the pistol upwards. So I am kind of rethinking which firearm to carry. I have a 40, but thinking about 10mm. Heavier powder load in the 10mm.
I have always wondered about a FN57 for bear defense with solids. Seems like a 5.7x28 with a solid would be pretty good. I have no experience with one. (I would if there were cheaper). Anyone have feedback that round. I have a 10mm but the 5.7 has always intrigued me.
The following are energy numbers out of the Hornady web-site. They had muzzle energy, 50 yd energy and 100 yd energy. I chose to calculate at the 25yd energy value as a relative value:
9mm Plus x 4"brl. 350#ft
357 Mag x 8"brl. 500#ft
41 Mag x 10"brl. 1000#ft
44 Mag x 7.5"brl. 890#ft
45 Colt x 4,75"brl. 430#ft
454 Casull x 7.5" brl. 1710#ft
460 S&W x 8.38"brl. 1915#ft
480 Ruger x 7.5"brl. 1170#ft
50 Action Expr. x 6"brl. 1250#ft
500 S&W x 8.5" brl. 2617#ft
Not a solution to what to use against a grizzly, but my method for protection is not to go invading his territory and space and putting myself in a terrible situation that I could lose. I used to surf years ago and it was kind of the same situation with the sharks. Mr shark was pretty much king of that environment and I was there just dangling my legs in his space. Now older and wiser, I dont go surfing. Nor do I want to be in grizzly territory.Cram your snubby down Mr Bear's throat, all the way to your shoulder and start pulling the trigger. He will be trying to spit your arm out and make you go away. If desired results are not obtained after a minute or two, just leave your arm and BOOGIE!
