Fort Scott Munitions built this 9mm load (part no. 9MM-125-SCVSSTPD) around a 125-grain solid copper bullet loaded to subsonic velocity, keeping every round below the speed of sound to minimize the sonic crack when fired through a suppressed pistol. Fort Scott Munitions machines the bullet from solid copper rather than a lead core and jacket, using their Tumble Upon Impact (TUI) design that’s engineered to tumble end over end after penetration rather than mushroom like a conventional hollow point. That gives the round a lead-free profile with a distinct terminal mechanism suited to suppressor-equipped 9mm pistols. In handgun ammunition built for suppressed and subsonic use, this is a purpose-engineered box.

Key Specifications

• The chambering is 9mm Luger, loaded to subsonic velocity for use with a suppressor.
• The bullet weighs 125 grains, a common subsonic weight for reliable cycling in semi-autos.
• The projectile is solid copper, with no lead core, giving a fully lead-free round.
• This is a Tumble Upon Impact (TUI) design, engineered to tumble rather than expand for its wound effect.
• Each box holds 20 rounds, packaged as part of a larger 25-box case.

Frequently Asked Questions

Why load this round to subsonic velocity? Staying below the speed of sound eliminates the sonic crack a bullet normally makes in flight, which matters most when firing through a suppressor.

Does this bullet expand like a hollow point? No. The TUI design is a solid copper projectile engineered to tumble after impact rather than mushroom, which is a different terminal mechanism than a traditional expanding hollow point.
