Ammunition capacity is a debatable point when it comes to a bear defense handgun, and it ultimately boils down to the individual situation. Most big revolvers hold five or six rounds. A factory double-stack 10mm will usually hold 15 rounds. Sure, in some situations, you’ll only have time to get one shot off, sometimes zero, but there are also very real possibilities of needing more than five or six rounds in the gun. I’ve seen several brown bears take between six and 13 rounds of .375 H&H before finally expiring. Often, even with rifles, when bears are hit in the body, they will spin, sometimes recovering and continuing on their path, but it usually slows them down, giving more time for additional shots. It’s incredible how fast ammo can run dry, and if faced with that situation, I want to be able to pump as many bullets into that bear as fast and accurately as I can.
