Derringer is a very popular small personal defense weapon. You can find many modifications of it on the Internet. The model is fully functional. It is designed to use functional 29mm hubs, which are posted on my profile.

Assembly:

Material:

- nail diameter 1.85 - 2 mm
- spring with written pens
- superglue
- sandpaper coarseness 250

Assembly is simple and problem-free. It is recommended to sand the inside of the chamber with sandpaper so that the moving parts move freely. The barrel lock spring holder must be glued in position on the lock axis to fit well into the barrel lock chamber. The barrel lock spring must be glued to the holder on the barrel lock axis. For a more precise fit of the round handle with two holes, use the axles made using a filament with a diameter of 1.75 mm.

If you find that the moving parts do not have enough force to return to their positions, stretch the springs and then test the functionality again. After rough assembly and verifying that all moving parts move freely and with enough force to return to their positions, the model can be glued together with super glue to hold it together.
