The P239® Tactical is the same pistol that was developed in response to demands from law enforcement and federal agents for a compact back-up pistol ideal for off duty concealed carry. Only this one comes with a threaded barrel, front cocking serrations on the slide, and the SRT Trigger System. The SRT (Short Reset Trigger) is designed to provide you the same great safety and smooth action of the SIG DA/SA with a comfortable reset that is 60% shorter for faster trigger return and surgical control during high speed shooting. The slim profile of this single-stack pistol provides easy concealment without sacrificing handling. The excellent characteristics of the P239 are the result of “performance engineering” and it’s one of the keys to all SIG SAUER® pistols.
