Anyone own a Glock 20 in 10mm? If so, what are your thoughts on the gun? Seems really powerful and cool, perhaps useful for defense against attacking felons or critters. If I get one it'd be with a .40 S&W barrel too so I can shoot the cheaper .40 S&W but keep the hot 10s for carry and moderate shooting. What do you all think about the Glock 20 10mm semi-automatic handgun?
