The Sig Sauer P290, produced from 2011 to 2017, is a subcompact handgun known for its polymer frame and stainless steel slide treated with a black Nitron finish. Chambered in 9×19mm Parabellum, the P290 features a durable polymer grip section and comes with a 6-round magazine as standard, with an optional 8-round magazine that includes an extended baseplate. The pistol's sights are tritium-illuminated Siglight Night Sights, and it also offers an optional laser sight for enhanced aiming. The P290 is notable for its double-action-only (DAO) trigger, which activates a hammer to fire the cartridge. This model includes interchangeable grip panels, allowing users to customize its appearance. In 2012, the P290 was succeeded by the P290RS, which introduced significant improvements, including a redesigned DAO trigger with "Restrike Capability." This feature allows users to pull the trigger a second time in the event of a misfire, eliminating the need to retract the slide. Other enhancements include modifications to the grip beavertail, an improved magazine baseplate with finger support, and a reshaped magazine release and slide hold-open lever. The P290RS is available in both 9mm and .380 ACP calibers and often comes with accessories such as a holster and extra grip panels.
