Rosco Manufacturing

This Rosco 7.5" 9MM Barrel was designed for Personal Defense Weapon (PDW) builds where the end user might run suppressed occasionally and need extended accuracy at distance from a compact platform. Twist rates have also been considered to optimize performance across a variety of rounds, including those you might use in your duty or concealed carry pistol, to promote cross-platform ballistic familiarity.
