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
Developed and tested by the Black Lotus Coalition, 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.
