A Glock 17 is seen in the hands of a few NYPD ESU officers as one of their main sidearms in tactical operations. It's also seen in a computer screen at a NYPD detective's office table in "A Giant Gun, Filled with Drugs" (S01E15). An injured security guard fires his Glock 17 at Alysa Darvin and her robbery crew in "Snow Angels" (S01E19). Isaac Proctor (Erik Jensen), an assassin working for Moriarty, uses a Glock 17 after he goes rogue in "The Woman" (S01E23).

A Glock 19 is used as one of the standard sidearms of uniformed NYPD officers. Serial killer Martin Ennis (Terry Kinney) takes a Glock 19 from a New York State Department of Corrections and Community Supervision guard after he's killed in "The Deductionist". Holmes shows off the same weapon to Ennis near the end of the same episode to see if he'll turn himself in or try to resist being captured alive.

Jamie Moriarty (Natalie Dormer) is seen with a compact pistol that resembles a Heckler & Koch USP Compact in "The Woman" (S1E23). Upon closer inspection, this pistol appears to be a resin prop replica.

This unknown MP5 was used in "Details" (Episode 1.16) during the attack on Detective Bell's sedan. The show does not depict exactly what type of MP5 is used, only that it has a rifled barrel and was fired in three-round bursts, instead of fully automatic.
