I've recenly read of this new hype conceal carry cartrige called 30 Super Carry. The article about it stated, that it contains the same practical properties as 9x19mm Luger, however since the case is smaller with aditional benefit of +1 or even +2 extra rounds of mag capacity in the same package.
I was courious about it, so i wanted to find a 3D model, measure or even print one dummy, to compare it to 9x19. As I was unable to find model online I decided to make one on my own.

Model has been made from "blueprint" I found online, with additional bonus o JHP projectile, boxer type primer and a (desparete :-D ) attempt to make a sferic proppelant.

I've also added components separately as well as model cuts should anyone want to make an above-life size educational model.
