Which U.S. law‑enforcement agencies have officially replaced the P320 and which pistol models they selected?
Executive summary
Several U.S. law‑enforcement organizations have publicly moved away from the SIG Sauer P320 platform; the clearest, documented replacements show a strong pivot toward Glock pistols—most notably ICE’s mandate to procure Glock 19 MOS pistols—while several police departments and transit agencies have switched to unspecified Glock models or Glock 17s depending on procurement choices and emergency purchases [1] [2] [3] [4].
1. ICE: a formal, documented switch to the Glock 19 MOS
The most explicit, agency‑level replacement comes from U.S. Immigration and Customs Enforcement, which issued memoranda directing discontinuation of all P320 models for carry and an acquisition decision to replace them with Glock 19 MOS pistols; reporting and acquisition notices confirm that ICE awarded a duty‑pistol contract to Glock and ordered Glock 19s as the replacement duty handgun [2] [1] [3].
2. Milwaukee Police Department: a near‑complete transition to Glock pistols
The Milwaukee Police Department publicly completed a departmentwide transition away from the SIG P320 and reported that approximately 95% of officers were carrying Glock pistols as their new service weapon after a union‑city agreement to replace P320s—coverage specifies “Glock pistols” rather than a single model in the reporting examined [5].
3. SEPTA and emergency Glock buys: Glock 17s as replacements in at least one transit agency
After an on‑duty unintentional discharge involving an issued P320, the Southeastern Pennsylvania Transportation Authority (SEPTA) made an emergency purchase of 350 Glock 17 pistols and holsters to replace the P320s, a concrete example of a local agency choosing a specific Glock model as a direct replacement [4].
4. Other law‑enforcement agencies that have pulled or paused P320s, and what’s not settled
Multiple state and local agencies across Alabama, Connecticut, Florida, Texas and Wisconsin have removed the P320 from service or otherwise paused use amid safety concerns, and federal entities such as Air Force Global Strike Command instituted pauses or halts pending review; however, many of those public actions amounted to bans or suspensions rather than fully documented, permanent procurements of a specific replacement model—coverage documents widespread withdrawals and pauses but does not uniformly identify which exact replacements, if any, every agency selected [6] [7] [2].
5. Patterns, caveats and the limits of available reporting
The pattern in the reporting is clear: where agencies have declared a firm replacement, they have tended to select Glock variants—ICE chose the Glock 19 MOS, SEPTA bought Glock 17s, and Milwaukee moved to Glocks generally—yet much of the national roll‑back activity consists of bans, pauses, or partial transitions rather than universally published, model‑level procurement awards, and numerous agencies that pulled the P320 have not released formal replacement contracts or model specifications in the articles reviewed [1] [3] [5] [4] [6]. Additionally, SIG Sauer and favorable outlets continue to defend the P320 platform and note continued military service of the M17/M18, meaning vendor messaging and litigation dynamics are influencing the narrative alongside agency safety directives [8] [7]. Reporting also shows that some occupational bodies and ranges banned the P320 for competition or training—actions that are policy decisions distinct from procurement replacements and do not necessarily imply a one‑to‑one switch to a different model [2].
Conclusion
Public, documented replacements of the P320 by U.S. law‑enforcement agencies most concretely include ICE’s move to Glock 19 MOS pistols, SEPTA’s emergency purchase of Glock 17s, and Milwaukee Police Department’s broad transition to Glock pistols; many other agencies have pulled or paused the P320 due to safety concerns but either have not publicly named a permanent replacement model or have made piecemeal decisions that reporting has not fully catalogued [1] [2] [3] [5] [4] [6] [7].
