The SIG Sauer P239 is a semi-automatic pistol designed and manufactured by SIG Sauer, GMBH and SIG Sauer, Exeter, NH. It is offered in three calibers: 9×19mm Parabellum, .357 SIG and .40 S&W.

With an overall length of 168 mm (6.6 in) and height of 132 mm (5.2 in), and weighing approximately 710–770 g (25–27 oz) empty (depending on caliber), the P239 has become popular in the United States as a concealed carry pistol.[1] Normal magazine capacity is 8 rounds (9×19mm) or 7 rounds (.357 SIG or .40 S&W).



The actions available are double-action only (DAO) or double/single action (DA/SA), as well as the newer DAK trigger system developed for law enforcement, which functions as a DAO trigger with a 6.5 lb (29 N) trigger pull. DA/SA pistols have a de-cocking lever on the left side of the frame in front of the slide-release. This lever lowers the hammer from cocked to de-cocked and engages a firing-pin safety, making the pistol safer to carry. With the hammer in the down position, the pistol can be fired by just pulling the trigger.

The SIG Anti-Snag or SAS version has a dehorned stainless steel slide with custom SIG wooden grips and the DAK trigger system. The "Generation 2" of the SAS variant features a DA/SA SRT (Short Reset Trigger) trigger and night sights, but with slimmer polymer grips.

The P239 Tactical version of the pistol features a black Nitron finish, a 4-inch threaded barrel, SRT, and night sights.[2]

A P239 with a "G" in the model number indicates the gun was issued to law enforcement and includes three magazines with the pistol.


SIG released an altered version of the double-action only (DAO) pistols called the DAK (for Double Action Kellermann, after the designer of the system, Harald Kellermann of Eckernförde, Germany).[3] The DAK capability is available in 220, 226, 229 and 239 models. When firing the pistol the first trigger pull is 6.5 lbs (compared to 10 pounds for the standard DAO). After the pistol fires and the trigger is released forward, the trigger has an intermediate reset point that is approximately halfway to the trigger at rest position. The trigger pull from this intermediate reset point is 8.5 lbs (38 N). If the trigger is released all the way forward, this will engage the primary trigger reset and have a trigger pull of 6.5 lbs (29 N). To engage the intermediate reset, the trigger must be held to the rear while the slide is cycled, either manually or by the recoil of a round being fired.


In 2004, the US Department of Homeland Security (DHS) Office of Immigration and Customs Enforcement (ICE) contracted with SIG-Sauer for the purchase of up to 65,000 pistols, among them DAO model .40 caliber P239s.[4] The US Navy's Naval Criminal Investigative Service (NCIS) has purchased P239 DAKs in .40 caliber (along with P229 DAKs) to replace their aging 9mm M-11 pistols.[5]
