Handguns

Smith & Wesson 6906

Gabriel's wife T.K. Law (Carla Gugino), takes out her Smith & Wesson 6906 to give to whom she thought was her husband, but turns out to be Yulaw.

Smith & Wesson 6906 - 9mm.

SIG-Sauer P220 Sport (dressed up as future gun)

A SIG-Sauer P220 sport model modified. Used by MVA Agent Evan Funsch (Jason Statham) and his fellow MVA Agent Harry Roedecker (Delroy Lindo). It's most likely their universe's common sidearm for MVA agents. It had a long compensator and some odd attachment for a flashlight/laser pointer. It was more of a target symbol than a point when seen on a target.

In the movie - they had to give it an alternate name. It's called the M590.

SIG-Sauer P220 Sport - .45 ACP.

Funsch (Statham) also briefly used an even more customized version of the gun at the end of the movie. He states directly, "My own design. Highly Modified M590 Hand-portable system. Fires 25 smart rounds per second. Multiple tracking modes plus the latest countermeasures. Each round carries a high explosive anti-personnel warhead with selectable fuse delays. Tracks. Enters. Pauses .1 microseconds. Then boom, Mixto Rojo."

Sphinx AT 380 pistol

When his Custom Modified M590 was destroyed, Funsch changes to a backup pistol. He called it the "Little Brother" of his Modified M590. So it can probably be surmised that it has similar capabilities as the larger version, such as the ammo type and tracking modes.

Heckler & Koch USP Match

The handgun of Yulaw (Jet Li) seen early in the movie, but was taken away when he was caught. It is customized like the SIGs used in the movie most likely because it came from the same universe.

Vektor CP-1

Seen in use by the guards of the MVA's universe. Yulaw stole one from a guard during his escape. He loses it later in the movie.

Shotguns

M26 MASS (Modular Accessory Shotgun System)

The M26 Modular Accessory Shotgun System are mounted under the M4A1 carbines carried by LAPD officers that escort Lawless in the Anubis Universe. The MASS in this film is the early version as later production models are slightly different.

Heckler & Koch FABARM

A Heckler & Koch FABARM shotgun is seen used by the LA Sheriff's Department of Gabriel's universe. One is seen bent by Gabriel.

Heckler & Koch FABARM -12 Gauge

Submachine Guns

Heckler & Koch MP5

Seen in use by security forces of the MVA's universe. These are kinda weird to tell what it is since it is heavily customized with a chrome barrel extending at the end and some of them had skeleton stocks like the H&K UMP's. The skeleton stock isn't the MP5k PDW folding stock. On other pictures - the stock seemed very similar to G36s but designed to be a non-folding stock.
