The CMMG Dissent MkG pistol in .45 ACP with an armor black finish and 6.5-inch barrel (brand part no. 45A4C0FAB) brings the classic .45 ACP bore to the ultra-compact, bufferless Dissent platform, sized to travel as a PDW-class pistol. CMMG runs a Compact Action-Radial Delayed Blowback operating system that eliminates the need for a buffer tube, and the 4140 chromoly steel barrel uses a 1:16 twist paired with a CMMG Zeroed Linear Compensator. The DISSENT PCC upper and forged MkG lower are both 7075-T6 aluminum, and a drop-in single-stage Zeroed trigger with an integrated trigger guard rounds out the build. Two 13-round Glock-pattern magazines ship with the pistol, and the design accepts widely available Glock magazines for ammunition compatibility. Among compact PDW-style .45 ACP semi-auto handguns, this Dissent MkG configuration favors shooters who want a truly compact, buffer-tube-free pistol build.
