I see a lot of “opinions” as we’re entitled to our own viewpoint. I posted earlier and continue to read the commentary. Ultimately the proof is in the pudding. I don’t know of anyone who has taken a grizz with a 460 Rowland (I personally carry an XD 45 converted to 460 & live in Alaska). But I do know a 10mm has dispatched one; enjoy the read:
A charging grizzly bear attack was stopped with a 10mm Glock pistol on Elmendorf-Richardson in September of 2018.
