The MOS (Modular Optic System) slide comes factory-cut with a Slimline optics footprint, allowing direct mounting of popular micro red-dot sights without additional milling. Front and rear serrations offer enhanced grip for press checks and slide manipulations.
A 3.41-inch Glock Marksman Barrel features enhanced polygonal rifling for reliable accuracy and easier maintenance. The barrel, slide, and frame share the CBMA-prefix serial, verifying component originality.
The reversible magazine release accommodates right- or left-handed shooters, while Glock’s Safe-Action system provides a consistent striker-fired trigger with integrated trigger safety. Polymer white-dot front and white U-notch rear sights supply a clear sight picture out of the box.
The Slimline single-slot rail accepts compact weapon lights or lasers, expanding the pistol’s defensive versatility without adding bulk. Austrian CIP and AT proof marks confirm factory testing and quality control.
