I'm no smith...
Are you referring to simple blowback type actions? If so, I know the .45 requires a locked breech/delayed blowback type action as the pressures are too high otherwise. This type of action also mitigates much of your felt recoil. I know that HiPoint and some Astra I can't remember have a 9x19 blowback pistol, but I think that's about as far as you can take it. Makarovs were made with fixed barrels and their accuracy is usually attributed to this unique feature. If you're talking about something else far beyond that, then I have no idea. I can hardly engineer a social event.
