The BA-40 Patriot is a semiautomatic pistol. Its chassis is molded and constructed of ballistic-grade plastics and the barrel, trigger and other metal parts, are made of non-ferrous alloys.
It is the standard-issue sidearm for all WEC armed services replacing the obsolete BA-20 in 2191. All employees during their initial enlistment period complete a handgun safety course. The Patriot is presented upon request or during all scheduled or unscheduled inspections. Guards are armed only with a BA-40.
It fires a caseless .40 shell and normally mounts a 20-round internal magazine.
There are few modifications of this model for varying amunition types, accomodated by cartridge and barrel adapters.
BA-41 is a variant of BA-40.
