PSMSA DIY Derringer - DIY 22wmr Cylinder

Practical Scrap Metal Small Arms vol 7 Model 2 Revolver kit from Excalibur. These are manually turned and index on the bottom cylinder. Six 22mags won’t fit, five would but wouldn’t index correctly, so four it is ! Their brass cratering into the breech face makes turning the cylinder difficult after firing. I’ve found dropping the hammer on a fired round 3 or 4 times is enough to hammer it back down so it can be rotated again. Not a complete success, but this is a novelty at best anyway.
