The Handgun is the official sidearm of the U.B.C.S. mercenaries in Resident Evil 3: Nemesis. The weapon is identified as a SIGPRO SP2009 in the examine screen.
The SIGPRO is essentially a copy of Jill's Beretta with a different skin, with the same capacity of 15 rounds.
The player can equip this weapon when playing as Carlos Oliveira, during his mission to find a vaccine for Jill.
Nikolai Zinoviev utilizes the SIGPRO as his primary weapon, while Brad Vickers is seen using it in the alley behind Bar Jack and then inside the bar.
Nikolai uses the SIGPRO as his only firearm in the mini-game, along with a knife. He can load the SIGPRO with special Enhanced Bullets.
"SIGPRO SP2009 It's mainly made of plastic and is very light. It uses 9mm parabellum rounds."
"Enhanced SIGPRO. It is loaded with enhanced 9mm parabellum rounds."
