Both the Glock 20 (10mm) and the Glock 21 (.45ACP) are Glock's large frame guns. The grip circumference is noticeably larger than that of the 9mm/.40 caliber weapon frames.

But that doesn’t necessarily mean it’s better. Whichever way you go, Glock has you covered. For now, I’m focused on one specific model: the Glock 20, a full-size 10mm pistol.
