Pretty much every cops sidearm....
Yep. The standard issue for police now is the Glock 45. I comes standard with a17 round mag. An officer came in wanting a backup for his newly issued Glock 45 and I sold him a Glock 26 with a 15 round magazine and magazine sleeve. He had been previously issued a Glock 22 in .40 S&W and his backup was a Glock 27 of the same caliber.
