Third-Generation Glock 17 pistols were for a long time the predominant weapon carried by almost all of the show's main male characters. FBI Supervisory Special Agent Derek Morgan (Shemar Moore) carried his Glock 17 with a Streamlight TLR-2 weaponlight/laser module. B.A.U. (Behavior Analysis Unit) Chief SSA Aaron Hotchner (Thomas Gibson) and Dr. Spencer Reid (Matthew Gray Gubler) were also both frequently seen with standard Glock 17's. Of these three individuals, only Hotchner continues to carry a Glock 17. Reid exchanged his Glock for a .357 Smith & Wesson Model 65 revolver in Season 4 while Morgan switched to a SIG-Sauer P226R (fitted with a TLR-1 Streamlight attachment) as his sidearm in Season 6. Other FBI agents and some police officers are seen with Glock 17 pistols.
A Glock 26 pistol is the duty weapon of the B.A.U.'s former 'Communications Liaison' (and now active profiler/analyst) SSA Jennifer 'J.J.' Jareau (A.J. Cook). The Glock 26 is also the backup weapon carried by both Aaron Hotchner (Thomas Gibson) and Derek Morgan (Shemar Moore), both carried in ankle holsters.
SSA David Rossi (Joe Mantegna) carries a Springfield Armory TRP, a model of which is used by the FBI's elite HRT, throughout the series, this suggests he may have been HRT/SWAT trained to use this weapon. Rossi also has a background of serving in the U.S. Marine Corps, which also 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. His SIG can be identified as the P226R by the tactical rail, redesigned grips and trigger.
Throughout the series, FBI SWAT and several local police tactical units carry M4A1 carbines, both standard models and variants with various accessories.
