Description
The Fort Scott Munitions Tumble Upon Impact (TUI) line is built around a patented monolithic solid copper spun projectile engineered to tumble when it strikes water-based tissue, creating a dynamic wound cavity without relying on a traditional jacketed hollow point. This subsonic 9mm Luger loading drives a 125 gr solid copper bullet at 950 fps for 250 ft lbs of muzzle energy, keeping the round below the speed of sound for subsonic applications.
Designed specifically for self-defense and home defense use, the TUI design relies on rotational dynamics rather than expansion to generate its wound channel. The all-copper construction means the projectile is completely lead-free, and the bullet is seated in a brass case loaded to subsonic velocities. That combination makes this round a natural fit for any full-size or compact 9mm pistol, including duty, concealed-carry, and home-defense firearms.
Fort Scott Munitions produces this ammunition as match-grade factory ammunition, with attention paid to consistent overall length, concentricity, and downrange performance.
