Speer loads the Lawman 115gr with a Total Metal Jacket bullet at 1,200 fps, producing 368 ft-lbs of energy from a standard-pressure 9mm case. The brass is boxer-primed and reloadable. TMJ differs from ordinary FMJ in one specific way: the jacket wraps completely around the bullet, covering the base where a standard FMJ leaves raw lead exposed. That exposed base on regular ball ammo melts under hot propellant gases and sends lead vapor into the air. Speer eliminates that surface entirely.

The enclosed base matters most when you shoot indoors. Combustion gases hit the back of the bullet during ignition, and bare lead at that contact point turns into fine airborne particles. In a ventilated bay, that particulate still accumulates over a long session. Speer pairs the TMJ bullet with CCI primers and a clean-burning powder charge, all produced under the Vista Outdoor roof. The result is less residue in the air and less fouling in the gun. A growing number of indoor facilities now require TMJ or equivalent enclosed-base ammunition, so the Lawman line gets you through the door at ranges with strict ammo policies.

At 115 grains, this is a light 9mm load with a quick recoil impulse. Muzzle flip stays low, and split times between shots come down compared to heavier 124gr or 147gr options. That makes it a solid pick for shooters working on speed drills or putting several hundred rounds downrange in one afternoon. Anyone who carries the Speer Gold Dot 115gr for self-defense gets a direct ballistic match here: same bullet weight, similar velocity profile, and comparable point of impact at defensive distances. You train with the Lawman and carry the Gold Dot without adjusting your sights or relearning your hold.
