The P239 was designed to meet the demands of law enforcement and federal agents for a slim, single-stack pistol for concealed carry, and it is available in 9mm, .357 Sig, and .40 S&W. The model reviewed here is the 9mm with the Concealed Carry Package. The SIG P239 is nicely sized for concealed carry, with dimensions similar to that of a Colt Officer’s Model. The pistol sports a 3.6 inch barrel, and weighs in at slightly less than 30 ounces empty. The gun is just large enough to permit a full grip and easy handling, even with larger hands.
