The 9KT uses a roller-delayed blowback operating system in a compact K-length format, built in the USA with a stamped steel receiver and a parkerized plus powder-coat finish. It retains the MP5 diopter sight system with a hooded front post and rotary rear drum for precise, repeatable adjustments.
The 5.83 inch steel barrel is nitrided and configured with an HK-pattern 3-lug plus 1/2x28 threads, capped by a knurled thread protector. The 1:10 inch right-hand twist supports common 9mm loads, and the dual-interface muzzle gives broad attachment flexibility.
Controls mirror the proven HK layout, including paddle and push-button magazine releases, an MP5K-style charging handle, and a manual safety selector. The SEF-marked polymer trigger housing shows S/E/F positions.
Upgrades on this example include a Vortex SPARC red dot with magnifier for fast sighting and a clear aiming point, and an SB Tactical dual-rod collapsible brace for compact carry and stable bracing. The K-length tubular, vented MP5K-style metal handguard/shroud maintains a compact footprint.
Factory specs list an overall length of approximately 13.38 inches and a weight around 4.8 pounds for the 9KT. This pistol ships with two 30-round translucent ETS magazines and includes PTR documentation, including a Quality Inspection sheet dated March 31, 2020.
