What kind of aded stress will these very high pressure loads put on the pistol and if the pistols are small hide out guns with short grips, how much more recoil will the shooter have to deal with?

I think with a barrel and slide that are beefy enough to handle the 9mm, a .30 cal super-hot round should be fine. My plan is to buy a Kel-Tec PF9 and make a new barrel for it, as well as make an insert for the slide to handle the smaller case, a longer extractor claw to grab the rim, and an ejector that can eject the case. I'll buy some 5.7x28mm brass and cut it down, find a mold for .308 caliber heeled pistol bullets (the 5.7 case is a straight-walled case .309 inches in diameter) and see if it works. If it works, I'll try a 1911 magazine or some other .45 auto magazine, that should almost make it a double-stack magazine. For a true double-stack, I'd need .54 inches inside the mag - maybe a .50 GI 1911 magazine? I was planning to cut away the grip anyway.
I think it would be a fun project. The only problem would be headspacing a rimless cartridge with a heeled bullet - you can't do it on the case mouth, and you can't do it on the rim. Extractor, maybe? I don't know. I'll have to think about it.
