Smith & Wesson Auto

Gaberiel's wife, TK, takes it to who she thought was Gabe but was Yulaw and used it to kill TK.

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

SIG-Sauer P220 sport model. Used used by Jason Statham and his partner who was played by 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 Hand-portable system and fires 25 smart rounds per second with multiple tracking modes plus the latest countermeasures. Each round carries an explosive anti-personel warhead with selectable fuse delays. Tracks. Enters. Paused .1 milisecond then boom Mixto rojo. And that is a direct qoute from the movie. Jason also used briefly an even more customized verison of the gun at the end of the movie.

Unknown handgun

When his SIG was lost, Jason changed to a backup pistol. He called it the "litte brother" of his primary handgun

H&K USP Match

Yulaw's handgun he was seen used 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.

H&K 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 the folding stocks like MP5K-PDWs.

Vector 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.
