First introduced in 1998, this compact pistol is a "cut-down" variant of the famous SIG-Sauer P220 pistol. Intended mostly for US market, this pistol is suitable for concealed carry and as a police backup weapon. The P245 has a traditional SIG-Sauer reliability, and, while somewhat heavy for a concealed gun, it offers a good recoil control. P245 is manufactured in Germany by the J. P. Sauer & Sohn company, which is a part of the international SIGARMS corporation.
P245 is a short recoil operated, locked breech pistol. It uses a typical Browning-style cam operated barrel, which locks into the ejection window in the slide. The slide is made from stamped steel, and has a separate breechblock held within the slide by the cross-pin. The frame is made from aluminum. The trigger is double action, with external hammer and a decocking lever on the left side of the frame. There's no manual safety, but P245 is provided with automatic firing pin safety.
