What’s Included
- Sig Sauer P239 Nitron .357 SIG pistol
- One factory 7-round stainless steel magazine
This P239 is chambered in .357 SIG, a caliber known for flat trajectory and high velocity in a defensive handgun. Its 3.6-inch barrel and single-stack magazine keep the profile slim without sacrificing ballistic performance.
The pistol uses Sig’s double-action/single-action trigger with a decocking lever, offering a consistent first-shot pull followed by crisp single-action follow-ups. An automatic firing-pin lock adds passive safety without extra levers to manipulate.
A stainless steel slide with Nitron matte-black finish rides on an aluminum-alloy frame, balancing strength with reduced carry weight. Rear serrations provide positive purchase for slide manipulation even with gloved or wet hands.
Fixed bar-dot combat sights deliver a clear sight picture. The textured one-piece polymer grip fills the hand while keeping the overall width narrow for easier concealment.
The SA4 serial prefix places this example in the later production run, giving buyers a discontinued model that retains modern ergonomics and support.
