Glock 30 vs Glock 21

In this video I'm doing a sit down gun review staring the Glock 21 & Glock 30 both chambered in .45AUTO. I also explain how I disassemble a Glock, and how to swap the barrel. For the Glock 21 I have a 10mm conversion barrel. Which allows me to have the best of both worlds in one firearm. #glock21 #glock30 #10mm
