Owners of the M9A4 Overlanding in Lunar Cerakote appreciate the Cerakote application for corrosion resistance during field and outdoor use, which fits the Overlanding theme. The 5.1-inch threaded barrel is a practical draw for those who want suppressor compatibility without a conversion kit, and the optics-ready slide avoids the need for a separate milling job.

The aluminum frame and beavertail get positive comments for comfort during extended range sessions, though some owners accustomed to lighter polymer-frame pistols note the extra weight. The 15-round capacity is accepted as adequate for a full-size pistol, but a few users wish for a higher-capacity option in the Overlanding line.

From a value standpoint, the M9A4 Overlanding carries a premium over the standard M9A4, and opinions split on whether the Cerakote finish alone justifies the difference. The build quality is generally praised, but trigger feel draws mixed reactions, with some owners swapping the stock trigger spring after initial break-in.
