Attached is the blueprint of the blank and barrel for TT-33 pistol (all measurements in metric).
What I am looking for is a commercially available barrel in 9mm Luger that this one can be made of.
I have one TT made in China in 9mm that shoots pretty well and the idea is to have a few more barrels for my other TT guns.
Of course the whole guns can be had for about $150, so the cost of buying and altering a barrel should be under $100 to justify the project.
