I recently bought a Glock 20, and I am looking to carry it exclusively for critter defense in the Rocky Mountains. I hear rumblings that it is not safe to shoot Underwood or Buffalo Bore out of it, which would really be a shame.

Is a stock Gen 4 Glock 20 able to safely handle these loads? If not, what do I need to do to get it to that point?

For those that carry Glock 20's for this purpose, what rounds do you carry?
