The Speer Lawman 9mm 135 Gr TMJ is a precision training cartridge purpose-built to mirror the recoil impulse and point-of-aim of Speer's Gold Dot 9mm 135 Gr self-defense load. Its Total Metal Jacket (TMJ) bullet fully encases the lead core - including the base - preventing hot gases from burning off exposed lead and significantly reducing airborne lead fouling. This makes it an outstanding choice for frequent training sessions especially on indoor ranges.Speer Lawman 9mm 135 Gr TMJ - 50 Rounds per BoxMuzzle Velocity: 1 120 fps | Muzzle Energy: 376 ft-lbs (4" test barrel)TMJ bullet fully encases lead core - minimizes airborne lead at the firing pointSubsonic profile - compatible with suppressed pistols and pistol-caliber carbinesBallistically matched to Speer Gold Dot 9mm 135 Gr defensive ammunitionReloadable brass casing with non-corrosive CCI Boxer primerClean-burning propellants for consistent chamber pressuresAt 1 120 fps this load runs just below the speed of sound making it an inherently subsonic option for those running suppressed handguns or pistol-caliber carbines. Its ballistic match to the Speer Gold Dot defensive line means shooters can train with the same feel and point-of-aim as their carry load - building genuine muscle memory under realistic conditions. Available in 50-round boxes and 1 000-round cases (20 boxes of 50).
