I'm planning a version for the Decker 9. Currently working on the Thompson .45/9 beta at AWCY?

I'm a little too excited.

So, from my experience with the NaG (I've built 3, 2 have exploded)...

Issues with loading/firing/extracting are usually down to the chamber geometry. You need to sand or file a slight cone into the chamber (for extraction) and a "feed ramp" into the top and bottom of the breech end of the chamber (for feeding).

I used rifled barrel liner for all my builds. The scuttlebutt is that a smooth 6mm ID 8mm OD stainless pipe will work better, because it produces less back pressure.

The best way to taper the chamber seems to be chucking the barrel into a drill and wrapping a piece of sand paper over a small rod, held at an angle, while the barrel spins.

I have a video on my odd sea firing the NaG https://odysee.com/@FieldExpedient:6/NaG01:e

Thank you, so much. I'm still relatively new to GunCAD, only a year so far.

Encouragement means a lot.

The brace is removable... but...

Here's my Tommy Decker with an 18" barrel. I haven't tested it yet, but I'm assured that it'll work.

I used the 5.5" chazel 380 liner. Got it with the kit from 3dPF

I was thinking the same. But no. These are the Pump & Dump 26.5 launcher.

I'm looking at the step file to see if I can mod it INTO a Shotgun, though.

Need the 9 also. I have plans for it.

Agreed with Maurice. .380 and 9mm are the same width bullet. Ecm a 9mm barrel. The chamber is smaller. When I measured a factory cut chamber, it was 17mm deep. But I'm not one hundred percent certain that'll work.

What project are these?

It's good to be here. Thanks for letting us sign up on the GCI instance.
