Combining the ever popular .45 caliber round and a well known design, there should be little surprise that the Glock 21 has found its way to Gun of the Week status.

Now up to a Gen4 build, the G21 is a duty size pistol that sports a capacity of 13+1. The new model has a handful of upgrades, including interchangeable backstraps.

The G21 is tough, reliable and a .45. What's not to like?
