357 Sig – 125 Gr TMJ-FN – Speer Lawman Cleanfire (54232) – 1000 Rounds

Speer Lawman is designed to mimic duty ammunition for training, and the Clean-Fire version reduces airborne lead exposure for indoor ranges. This listing is Speer Lawman Clean-Fire 357 SIG 125 grain total metal jacket flat nose ammo, MPN 54232, sold as a 1,000 round case for agencies and individual 357 SIG shooters.

Speer rates this load at 1,350 fps with 506 ft-lbs of muzzle energy, matching the performance of common 125 grain 357 SIG duty loads. The total metal jacket encloses the lead core, including the base, while Clean-Fire primers are designed to eliminate heavy metals such as lead from the priming compound. Together they reduce airborne lead at the firing line. The flat nose profile helps feeding in the bottleneck 357 SIG. This is training ammunition. It does not expand, so it is not a defensive load.

This ammunition fits pistols chambered in 357 SIG, including the Glock 31, 32, and 33, SIG Sauer P226, P229, P239, and P320 in 357 SIG, and Springfield XD models offered in the caliber. A common question is whether indoor ranges require Clean-Fire or TMJ ammo. Some do, and lead-reduced ammunition is a courtesy to range staff even where it is not required. Another common question is whether 357 SIG practice ammo should match duty ammo velocity. Matching velocity and bullet weight keeps recoil and point of impact consistent between training and duty.

Speer 54232 is new production ammunition, not reloads, made in the USA by Speer in Lewiston, Idaho. Each round uses a reloadable brass case with a boxer primer and non-corrosive priming. This case ships as 20 boxes of 50 rounds for a total of 1,000 rounds from one lot, sized for qualification cycles and regular indoor practice. Because 357 SIG can be hard to find locally, buying a full case keeps you training without gaps, and one lot keeps point of impact consistent.
