Thread: Shotgun-9mm thing

762mm is minimum. Make it 763mm with a full-length 9mm barrel pinned inside the shotgun tube. Probably best to do in a 20ga or similar as a 12ga with a 9mm tube filling it out might get Heavy. Also make sure the action can take the pressure.... pretty sure SAAMI max for 9mm is much higher than any shotshell cartridge

Maybe so but it is bearing on much less area.
IE 100psi on one square inch is 100 pounds and the base of both differ in large amounts.
A smart cookie like yourself would also know that half the bore size or case head dia doesn't mean half the thrust or pressure.

yeah just be sure that's it's safe is all I'm saying


a VFG is a vertical foregrip.
