The GLOCK 20 SF combines the SF (Short Frame) design with the powerful 10 mm Auto cartridge making the frame more comfortable and significantly enhancing controllability and accuracy. The SF design reduces the circumference of the receiver at the rear offering increased ease-of-use and control"" especially to shooters with smaller hands. The GLOCK 20 SF dimensions also provide a long sight radius for better precision. Includes two 10-round magazines.
