In this leathercraft video, I make a custom leather pistol case / range bag for my 9mm Smith & Wesson model 3913. My goal was to make a protective case that didn't obviously look like it held a gun, store all the extra magazines that I had for it, and permit quick access while carrying. The extra ammo storage was more of a bonus feature utilizing space that would have otherwise been wasted. There's enough to reload the entire bag.

All material from Tandy Leather
Laser is a Creality CS Falcon 10W
The strap is a surplus AKM sling
