The UTAS UTS-15 is a 12 gauge pump-action shotgun made by UTAŞ Defense of Turkey, with two 7-round magazine tubes that can feed in an alternating or selecting pattern.

The UTS-15 was developed as a result of a request to UTAS made by Smith & Wesson in 2006 to develop "the ultimate police shotgun".

Smith & Wesson's criteria for the shotgun were: 12-Gauge, pump-action, less than 30" overall length, and 13-round minimum capacity.

The UTS-15 has a 28.3" overall length with an 18.5" barrel, chambered for 2½", 2¾", and 3" magnum ammunition. Constructed primarily of fiber-reinforced injection molded polymer, the UTS-15 weighs 6.9 lbs.

Additionally, there is a top-mounted picatinny rail for the mounting of a wide variety of both iron and optical sights, coupled with Beretta-style barrel threading for choke tubes.

The following features are standard on all UTS-15 models:

Due to its unique design, the UTS-15 became an easily recognizable weapon within the firearms culture and was reviewed by several different sources. However, over time the UTS-15 became the subject of harsh criticism in the firearms industry developing a reputation for being plagued by numerous malfunctions (primarily failure to feed and failure to extract). UTAS attempted to correct these issues by developing a generation 2 and generation 3 variant of the UTS-15 that were supposed to correct the reliability issue.
