In 2017, Kahr Arms introduced the "S" Series, which includes two 9mm pistols: the S9093 and the ST9093. These pistols have a redesigned magazine base and grip and come with a limited lifetime warranty and two magazines. The S9093 has a 3.6" barrel with conventional rifling, an overall length of 5.9", and a height of 4.5". It features white 3-dot sights, front serrations on the slide, an accessory rail, and an ID tag on the grip. The capacity is 7+1 with two 7-round magazines included. The ST9093 has a 4" barrel, an overall length of 6.5", and a height of 5.08". It shares similar features with the S9093, including white 3-dot sights, front serrations on the slide, an accessory rail, and an ID tag on the grip. The capacity is 8+1 with two 8-round magazines included. Both pistols operate with a trigger cocking DAO, "Safe-Cam" Action, lock breech with "Browning-type" recoil lug, and a passive striker block with no magazine disconnect. The frame is made of black polymer with an accessory rail, and the slide is matte stainless steel with front serrations. The front sight is pinned in polymer, and the rear sight is a white two-dot sight. The Kahr "S" Series pistols are designed with reliability and functionality in mind, making them suitable choices for concealed carry and personal defense.
