Ammo Overview

Manufacturer - Speer Lawman
Bullet - 125 grain total-metal jacket (TMJ)
Casing - Boxer-primed brass


It’s no surprise to those who are in the industry that Speer has such a well behaved, consistent product line in the Lawman line of their ammunition portfolio. They’ve been gathering data and honing their craft for decades on the back of law enforcement contracts that have perennially been a big part of their revenue stream with their consumer cartridge lines producing well also. The company is generally a top three contract holder with law enforcement agencies, and of late has been the number one seller by volume to LE contracts of any supplier in the USA.

All these contracts allow them some unique insights to what it takes to make a round that can keep hundreds of thousands of police officers and corrections officers and special agents happy on the range. It translates directly to Speer’s success in the civilian market.

This is the .357 Sig round that features a copper clad TMJ (total metal jacket) projectile in 125 grain weight with a Boxer primed brass case that is hot enough to cycle all of the mainstream production firearms in the caliber, but not so hot as to be annoying to shoot. It’s a bit more expensive than the cheapest ammunition but for the crowd who wants to buy 100% made in the USA, or who knows the brand and wants the peace of mind of shooting ammunition that works every single time: Speer Lawman is the obvious choice.

A: No sir, it will not. The 357 SIG was designed to mimic the performance of the 357 Magnum, but it is an extremely different cartridge. Main difference is the 357 SIG has rimless case because it is meant for a semi-auto, but there are many other reasons your revolver won't accept this round. I regret we haven't got any 38 Special or 357 Magnum for you in stock at the moment, but we do update our inventory frequently!

A: No sir, I'm afraid not! The 357 SIG is a semi-automatic pistol cartridge which was developed to emulate the performance of the 357 Mag, but it's not actually compatible with those firearms. Your rifle can fire 357 Mag, 38 Special and 38 Special +P. I regret that we haven't got any ammo in stock for you at the moment, but we do update our inventory very often!
