Performance and handling
The 9mm chambering balances terminal performance, controllability, and ammunition availability. With a 4.5 inch barrel, expect better muzzle velocity and point-of-impact stability compared with shorter-barreled compact pistols, and a sight radius that helps shooters deliver tighter groups. The lightweight construction reduces carry fatigue while retaining enough mass to keep recoil predictable during rapid strings.
Ergonomics and magazines
Grip geometry on the STK100 is designed for consistent hand placement with a magazineable 17-round capacity that suits both defensive and range use. The optics ready slide is useful for those who plan to pair the pistol with a red dot for faster target acquisition.
