Mustang Arms "Mark II"

Mustang Arms "Mark II" is a powerful autoloader machined to very close tolerances. Using the latest computer-aided design techniques, the Mark 11 is ergonomically and technically advanced. It sports a 16.5cm barrel with a ported compensator, but its most unusual feature is the magazine: Although a standard 12-round clip is available, each Mark II comes with a 20-round "banana" mag. This handgun is popular with many police units for its "staying power"-that is to say, magazine capacity. Patrol officers commonly carry five twelve-round magazines of 11 mm AP, plus one up the spout; the banana clip is normally used by SWAT, entry teams, and military special-ops units.

Note: The tolerances are a little too tight. If the gun is dropped on a hard surface, Reliability drops to ST; if the weapon goes more than one day without cleaning in a "dirty" environment, Reliability drops to ST. Reliabillity also drops one level for every 24 rounds fired without cleaning.
