==SIG-Sauer P226R==
In his new cover identity as an NYPD detective, John Reese ([[Jim Caviezel]]) is seen carrying his [[SIG-Sauer P226R]] in Season 4's premiere "Panopticon" (S4E01). He isn't seen using the pistol again until "Prophets" (S4E05).

==SIG-Sauer P229R==
In a continuity error, Root appears to pull out a [[SIG-Sauer P229R]] alongside a Smith & Wesson 3914 from behind her back near the end of "Prophets" (S4E05). The pistol later turns into a Smith & Wesson M&P Shield. Several of the Samaritan operatives are armed with the pistol in the episode. Brooks (Theodora Wooley) and Devon Grice ([[Nick Tarabay]]) are armed with the P229R as their main sidearm, first seen near the end of "Honor Among Thieves" (S4E07). This pistol also appears to be used by NYPD Internal Affairs officer Dani Silva (Adria Arjona) in "Point of Origin" (S4E08) as her main sidearm and by Martine ([[Cara Buono]]) in "The Devil You Know" (S4E09). In "Skip" (S4E18), Francesca “Frankie” Wells ([[Katheryn Winnick]]) is seen using a [[SIG-Sauer P229R]]. Control ([[Camryn Manheim]]) uses it throughout "Asylum" to execute pro-Samaritan moles.

==Glock 17==
The [[Glock 17]] appears to be the handgun carried by Reese, now in his cover identity as an NYPD detective beginning in "Wingman" (S4E03). It also appears that Det. Lionel Fusco ([[Kevin Chapman]]) also carries this pistol. New York Police Academy cadets are seen using Glocks that fire paintballs in "Point of Origin" (S4E08). Some NYPD officers are seen with it in "If-Then-Else" (S4E11). Albert Weiss in "M.I.A." (S4E13) briefly seizes Fusco's sidearm before he gets gunned down. Claire Mahoney uses it after being recruited to Samaritan's forces, first seen in "Q&A" (S4E15).

In reality, the Glock 19 is the only Glock approved for onduty carry by NYPD officers.
