SNT Motiv booth, SHOT Show 2026. While everyone else was drooling over the Daewoo K7 at the same booth, I noticed an even more interesting firearm. The SNT Motiv STSM21.
Originally unveiled just in the last 5 years, the STSM21 was showcased at events like DX Korea and later international exhibitions such as IDEX 2025 and MSPO 2025. The design definitely draws inspiration from modern trends, resembling elements of the SIG MPX in its overall layout while incorporating a delayed blowback operating system for improved control and reliability over simple, clunkier blowback designs.
It looks like it shares a lot of similarities with the also-new SNT Motiv K13A1, which is SNT’s answer to the HK416. These include oversize, ambidextrous mag releases and optics-ready top rail.
