    Ouestion 1. What is the internal dimension in mm of a GLOCK BARREL?
    What dimension do custom barrel makers use?

    Question 2. What is the maximun pressure that is consider safe for
    a Glock barrel.
    What is the maximun pressure that custom barrel say are
    safe for their barrels.

    Someone else will have to address the pressure question specifically, but I'll bet the answer is: 'depends on the caliber of the gun'.

    Different caliber rounds generate different pressures, and chamber of the gun will be built to support that need. Are you asking specifically about the .40 S&W?

    Maybe too obvious, but I'll post it anyway...

    The internal diameter of the barrel is the same measurement as the caliber a gun is chambered for... ie:
    a 9mm pistol has a 9mm internal barrel diameter
    a 10mm pistol (or .40 S&W) - 10mm,
    a .45 is .45 inches, so do the conversion from inches to millimeters and you get .45 x 25.4 = 11.43mm

    Might be a few thousandths of an inch difference, but this is pretty close.

    Since you're posting in the .40 club forum I'm guessing you're wondering about (maybe?) the diameter of the chamber, as opposed to the barrel? Glock chambers its pistols rather loosely, relative to other makers, but I don't know those measurements off the top of my head.
