The functionality of the StA19 is almost identical to its predecessor, and its most distinctive features -- a front-mounted drum magazine and Luger-inspired cocking mechanism -- remain intact. The body of the handgun has been redesigned to take a more angular, downward shape that does a better job of countering recoil. The Reigner is also one of only a handful of Helghast weapons that does not feature a bullpup design. The StA19 can be outfitted with a variety of attachments, including a silencer for those who want to run a stealthier loadout.
