The Fort Scott Munitions TUI (Tumble Upon Impact) 9mm Luger represents a breakthrough in solid copper projectile design, engineered to maximize terminal performance through controlled tumbling action. This 115-grain ammunition delivers consistent expansion and energy transfer while maintaining the penetration advantages of monolithic copper construction.
What Makes This Different
Unlike traditional hollow point ammunition that relies on expansion, the TUI design creates a tumbling effect upon impact that increases the wound channel diameter. The solid copper construction eliminates lead exposure concerns while providing consistent performance across temperature extremes. The TPD-9 coating reduces barrel fouling and enhances feeding reliability in semi-automatic firearms.
Key Features
- 115-grain solid copper spun projectile with tumble-upon-impact design
- TPD-9 coating for reduced friction and improved feeding
- Lead-free construction eliminates toxic metal exposure
- Consistent 1,150 fps muzzle velocity from 4-inch barrel
- 20 rounds per box, 25 boxes per case (500 total rounds)
- Compatible with all 9mm Luger chambered firearms
- Reloadable brass cases with boxer primers
The TUI projectile maintains structural integrity through barriers while creating maximum tissue disruption upon impact with soft targets. Law enforcement agencies report reliable feeding in duty pistols including Glock, Smith & Wesson M&P, and SIG Sauer platforms. The solid copper construction provides consistent accuracy with reduced temperature sensitivity compared to lead-core alternatives.
