Smith and Wesson J Frame Pocket Carry Holster.

thingiverse

This is a pocket carry holster for any J frame revolver. I've tested it on a Models 60, 642, and 638. It is designed to fit tightly, and to stay on the gun when you draw. Apart from reloading obviously the action works perfectly and without interference from the holster. The gap at the top is a vent for the forcing cone so be aware of this if you remix as blocking the release of gasses while firing could break the holster and blow pieces of plastic all over the damned place. So, like, don't do that. Printed with five perimeters, 3d honecomb infill at 40%.
