Source .STEP files only. No STL mesh files so that enthusiasts can manipulate, edit, and remix to their hearts content.

Confirm barrel and retainer dimensions for your barrel stock before printing your mileage may vary.

I have been sitting on this project for years. If I don't spark some interest from this post, then I will totally abandon it.
This is a simple single shot that can use 45/410 chaszel liner, .22 protobarrel, 10/22 Ruger Barrel, steel pipe for 410 barrel, or Gatlatl. Barrel retainers can be remixed for almost any pistol caliber.
This design has the ability to be gunpart free. You can ECM a barrel instead of using barrel or liner.
Striker Spring is a small piece of AK recoil spring or equivalent.
It has blown up with 357 mag but that could be due to piercing the primer. Don't do that. Verify your firing pin protrusion. This is totally undocumented and unsupported. If you don't know what the firing pin protrusion should be. DON'T BUILD IT
Hardware is whatever safely fits.
Firing Pin can be a drill bit, screw, or hardened rod.
Breech plate can be stack of dimes, a piece of bolt, or steel round bar that fits the hole. Use one of the many 3d printed centerfire dime jigs out there drilling your hole.
If you don't know what your are doing then don't build this.
NFA parts are for example only.
Don't crime!
Don't be stupid, Don't build this. This is published strictly for informational purposes.
