The P239® SAS Gen 2, joining the recently updated P229® and P220® Carry versions, features a melt treatment on frame & slide, SRT Trigger System, SIGLITE® Night Sights, and black polymer grips. The slide features an engraved SIG SAUER® Custom Shop logo. The Generation 2 SAS is available in a Nitron or Two-Tone version. The P239® SAS Gen 2 comes in .9mm, .357SIG, and .40S&W calibers. This P239 pistol from the SIG SAUER Custom Shop has gone through a radical dehorning process resulting in an ultra smooth, snag free profile that’s ideal for concealed carry.
