The use of a handgun to ward off a bear attack is proven. It is not uncommon for aggressive bears to climb up your bowhunting tree stand with you in it or perhaps follow you back to your truck at night or a wounded bear attacks during recovery. 

Below, find an article with documented incidents where handguns were 98% effective on all bear species black, brown, grizzly and polar. 

Handgun Defenses Against Bear Attacks – 170 Documented Incidents, 98% Effective

Unfortunately, my new 10mm Glock 20 has set of daylight sights which makes the Glock defense use in dim light or darkness difficult at best.  I swapped them out for cost effective Tritium sights so I can see them in darkness.

I purchased a simple set of TRUGLO tritium sights for around $55 bucks. Not a bad price. Take the top slide off, remove the spring and barrel to get to the front sight nut and prep to remove the rear sight. 

You will need to purchase a tool for the front sight nut. 

and at least a push tool or bench vise and a wood or brass punch as in the video above. 

Next, is a holster for my Glock. 

I need instant access for a possible aggressive bear attack, thus I purchased a heat molded chest holster called the Kenai from Gunfighters, Inc. Cost $160.00

The first time the holster gripped the pistol, hearing a click,  I wasn’t able to pull it out without using great force. The Kenai literature instructed to carefully use a heat gun on the click/grip area.  Luckily, I had a heat gun. It worked.  Now, after heat adjusting, I can readily pull the pistol yet keep it secure.

Some folks find that a chest held binocular case can interfere with the draw of the pistol.  However, the holster can be adjusted to allow fast access. Below is  my Vortex Bino’s case with my Glock 20.  The bino case is huge, perhaps too big to wear. The pistol draw needs both hands. One hand to hold the holster base, while my right hand draws the pistol.

I will holster and practice drawing and shooting it with my binoculars on and off. If I’m on a bear stand in a tree, I will likely not wear the bino case. 

Below this video pitts the 10mm against the 44 magnum. 

A few year back I also did a 44 mag video below. In that fishing scenario, the 44 mag already drawn on an approaching bear, worked for the first shot but the recoil raised the pistol losing fractions of seconds to get back on target. 

Good Hunting!
