Harlot [1.0] Build Kit

Harlot [1.0] Overview

The Harlot isn’t trying to be something it’s not. It’s a simple, reliable, single-shot .22LR derringer that does exactly what it’s supposed to do. No complicated assembly. No hunting for obscure parts. No specialized machining equipment.

For under $30, you get every non-printed component required to complete your build. Print the files, open the box, and get to work.

What Makes the Harlot Different

Beginner-Friendly Design
The Harlot was engineered from the ground up for accessibility. If you can operate a 3D printer and turn a screwdriver, you can build this pistol. The break-action design is mechanically straightforward, and the assembly process requires no press-fitting, no drilling, and no machining beyond basic deburring.

Minimal Parts, Maximum Function
While other 3D printed designs require dozens of components and multiple hardware runs, the Harlot keeps it simple: a rifled barrel liner, a spring, and standard M3 hardware. That’s it. Everything ships in one kit.

Harlots Proven Reliability
, the Harlot has been refined through extensive community feedback. The current 1.0 release includes reinforced components, improved fitment tolerances, and a chamber pressure blow-off safety feature.

NFA Compliant Options
The file package includes a grip spacer designed to accommodate the legally required 3.7oz of metal weight, keeping your build compliant with federal regulations without additional engineering on your part.
