The Glock 20 is the 10mm powerhouse from Glock, build specifically for the 10mm, one of the most powerful rounds for a practical semi-automatic pistol. The G20 is not for little girls, but it is certainly manageable. I gave my new G20SF a great workout the other day and here are the results. The Buffalo Bore was particularly fun to shoot. What's been your experience with the G20? LINK TO VIDEO HERE. '
