SIG SAUER P320 For Sale
SIG SAUER P320 m18 for sale
The SIG Sauer P320 for sale is a modular semi-automatic pistol made by SIG Sauer, Inc., the company’s American branch. It is a further development of the SIG Sauer P250, utilizing a striker-fired mechanism in lieu of a double action only hammer system. The P320 can be chambered in 9×19mm Parabellum, .357 SIG, .40 S&W, and .45 ACP, and can be easily converted from one caliber to another; a change from .357 SIG to .40 S&W requires only a barrel change; a change between 9mm to .357 SIG or .40 S&W and vice versa are accomplished using a caliber exchange kit.
The P320 chambered in 9×19mm Parabellum was introduced in the North American market on 15 January 2014, followed by the .45 ACP compact model at the SHOT Show in January 2015. On 19 January 2017, it was announced that a customized version of the SIG Sauer P320 had won the United States Army’s XM17 Modular Handgun System competition. The full-sized model will be known as the M17 and the carry-sized model will be known as the M18.
The P320 was designed to be ambidextrous in handling, sporting a catch lever on both sides of the slide and user-reversible magazine release, and all other operating controls are designed so they can be operated from either side. The firearm can be field stripped with no tools. Additionally, the firearm can also be field stripped without depressing the trigger, an additional safety feature to prevent negligent discharge of the weapon.The fire control unit is removable, allowing to switch to a different frame size.

Initial production models of the P320 were found to have a “drop safety” issue if the firearm was dropped at a specific angle, potentially causing it to discharge. SIG Sauer has since refitted the P320 to make it drop safe and offers a voluntary upgrade program for early P320s.
Further information: § Drop firing problem
Apart from its initial issues, the P320 has proven itself to be an extremely reliable pistol for civilian, law enforcement and military use. Many police departments in the US and around the world have started issuing their officers P320s.
A Canadian special forces counterterrorism unit, Joint Task Force 2 (JTF-2), withdrew the P320 following a misfire that injured a soldier during a training exercise in November 2020; JTF-2 was the only Canadian military unit using the P320. A full enquiry exonerated the pistol and in June 2021 found that the weapon was not responsible for the accidental discharge, instead a holster for a different handgun model was being used. This ultimately was culpable for the negligent discharge
