Criminal Minds - Season 10
The following weapons were used in Season 10 of the television series Criminal Minds:
B.A.U. (Behavior Analysis Unit) Chief SSA Aaron Hotchner (Thomas Gibson) carries a third-generation Glock 17 as his duty sidearm. Other FBI agents and some police officers are seen with Glock 17 pistols.
Springfield Custom Professional 1911-A1
SSA David Rossi (Joe Mantegna) carries a Springfield Custom Professional 1911-A1 throughout the series. Rossi has a background of serving in the U.S. Marine Corps, which possibly helps explain his use of a 1911-type pistol.
SSA Derek Morgan (Shemar Moore) carries a SIG-Sauer P226R fitted with a Streamlight TLR-1 weaponlight as his duty sidearm. His SIG can be identified as the P226R by the tactical rail, redesigned grips and trigger. A SIG-Sauer P226R also appears to be the handgun carried by SSA Jack Garrett (Gary Sinise) in "Beyond Borders" (S10E19).
Interestingly, Gary Sinise, playing the role of SSA Jack Garrett, continues to carry a P226R in Criminal Minds: Beyond Borders, a spin-off of the series of which the episode "Beyond Borders" acts a back-door pilot.
Beretta 92FS pistols are used by many characters in the series, including criminals and police officers.
Smith & Wesson Model 65
Rifles / Carbines
Throughout the series, FBI SWAT and several local police tactical units carry M4A1 carbines, both standard models and variants with various accessories.
