The Mk23 version of the K100 takes all of the features which make the K100 the cornerstone of our handgun range, and improves them even further.The K100 comes optics ready with four mounting plates included in the box. The gun is easier to manipulate thanks to an enhanced grip texture and the new design of slid serrations affords a more positive grip. Different color options for the frame are available.
