Modified Bryar Pistol

Actually a Bryar rifle with stock and muzzle sawed. A fairly standard, relatively accurate blaster pistol with one exception: It had the ability to "charge up" and one fire large blast as opposed to faster, weaker ones. This had no detrimental effects on the gun or it's accuracy, but it did consume ammunition at a much higher rate than normal. The Bryar Pistol was the preferred weapon of Kyle Katarn until he adopted a lightsaber as part of his Jedi training. Katarn continued to carry it as a backup.

Behind the scenes
The name is an invention of Justin Chin, inspired by the composer Gavin Bryars.
