LEHIGH DEFENSE - 9MM - 90 GR - FLUID TRANSFER MONOLITHIC - 20 RDS/BOX
The Lehigh Defense 9mm 90 Grain Fluid Transfer Monolithic (FTM) load delivers elite-level terminal performance through a precision-machined, solid-copper projectile engineered to create devastating hydraulic energy transfer in soft tissue — making it one of the most technologically advanced self-defense rounds available today.
- Muzzle velocity of 1,300 FPS from a 4" barrel for flat, fast trajectory
- 338 ft-lbs of muzzle energy from a lightweight 90-grain projectile
- Fluid Transfer Monolithic design channels hydraulic pressure for maximum damage
- Solid copper construction eliminates jacket separation and ensures consistent performance
- Supersonic, brass-cased load engineered for reliable feeding in compact pistols
- 20-round box — ideal for carry rotation, testing, or stockpiling defensive ammo
Who This Is For
This ammunition is purpose-built for concealed carry holders, home defenders, and serious shooters who demand the absolute best in terminal ballistics. If you rely on a compact or subcompact 9mm pistol — such as a Glock 43, SIG P365, or Springfield Hellcat — and want a round that feeds flawlessly while delivering exceptional stopping power from a short barrel, the Lehigh Defense FTM 90gr is an outstanding choice. It's also popular among those who prefer lead-free, solid-copper projectiles for both performance and environmental considerations.

Frequently Asked Questions
How does the Fluid Transfer Monolithic bullet work compared to a traditional hollow point?
Unlike a hollow point that relies on expansion after impact, the Lehigh Defense FTM bullet uses precision-machined channels in its solid copper nose to force hydraulic pressure outward into surrounding soft tissue at the moment of impact. This creates multiple simultaneous wound channels without depending on fluid entering a cavity to initiate expansion — making it highly effective even through intermediate barriers, light clothing, or at reduced velocities from short barrels.
Will this ammunition feed reliably in compact and subcompact 9mm pistols?
Yes. Lehigh Defense specifically engineers the FTM profile for reliable feeding in a wide range of semi-automatic pistols, including compact and subcompact platforms such as the Glock 43/43X, SIG Sauer P365, Smith & Wesson Shield, and similar carry pistols. The smooth ogive and consistent case dimensions are designed to chamber without hesitation, even in tighter-toleranced defensive handguns.
Is this load appropriate for use in suppressed 9mm firearms?
This particular load is supersonic at 1,300 FPS, which means it will produce a supersonic crack when fired — even through a suppressor — and is not designed as a subsonic round. Lehigh Defense does offer dedicated subsonic FTM loads for suppressed use. However, the solid copper, unjacketed design produces minimal copper fouling and performs well mechanically in suppressor-equipped hosts. Always verify your suppressor's rated caliber and pressure tolerances before use.
