idk, a machine tight fit on the bolt, without any gaskets, should be a good enough seal to work as an effective air piston. could do it on the back end of the bolt, with a few gas check rings.

i'd love to see a modern 7.62 tokarev catridge.

based on one of the long 9mm brass blanks (for matched capacity). near-straight wall for stacking, with a pinch of taper for extraction. rimless.

also have some funpics

actually a good question since the OAL is 3mm longer than 10mm, guess there was some space left in there? or i might have got a miss-labeled pic of a 9x25 Dillon conversion.

theres a dozen people on youtube showing how you can do this in a garage with basically nothing. pistol and SMG barrels are short enough that deep drilling isn't even a concern.

if you're so hard up that common DOM tubing isn't available, thick brass stock will work, if not last long.

it's not really "proprietary" when there's 3rd party producers.

they picked the P320 because SIG USA is heebs and they sucked the right political dick. i'm still bottom bamboozled by the P365. they employ talented designers, but shave every edge off the coin. it is so cheaped out the design is compromised. MIM parts where they shouldn't be.
