    Good photo shop skills.:thumbup:

    Id go 5mm over min legal length as your insert is short as so you gain nothing by extra length except perhaps smoother swing which is sort of irellevent in this case?

    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.

    I've seen it done before on a 12g with a 6" section of .38 special barrel inserted at the breach end, then the remainder of the 12g barrel was turned into an intergraded suppressor with baffles added. The rimmed .38 case is easier to extract, and all that was required was an extra bit braised onto the existing ejector/extractor.

    That sounds pretty decent.

    Should I lop the barrel off with a grinder or hacksaw?
