The Meridian Munitions Wheelgun-38 is a six-shot double-action revolver chambered in .38 Special, built with a carbon steel frame and a four-inch barrel. It is the cheapest revolver available in GLMZ, manufactured using the same cost-minimization approach that defines all Meridian Munitions products. The finish is a flat black oxide that provides minimal corrosion resistance, and the grips are hard rubber with no contouring.

The Roundhouse exists because a significant portion of GLMZ's Shelf population distrusts semi-automatic pistols. Revolvers are mechanically simpler — no magazines to lose, no slides to rack, no safeties to forget. For residents with minimal firearms training, the revolver's simplicity is its primary feature: load it, point it, pull the trigger. The heavy double-action trigger pull serves as both a safety mechanism and a quality-control compromise.

The weapon's reliability is its saving grace. Where a Payday might jam, a Roundhouse will fire. The .38 Special round provides adequate stopping power against unarmored targets, and the six-round cylinder doesn't require counting rounds or managing reloads under stress. For Shelf residents who want 'a gun that works when I need it to work,' the Roundhouse delivers on that promise and nothing more.
