    Default Jarvis barrel for Glock marked .400, a little help please.

    I'm getting ready to sell a Glock 10mm that I have. When I bought it, it had three extra barrels. I'm looking at one of the barrels and it's marked "Jarvis .400" which seem an odd way to mark a 10mm. I thought it might be .400 CorBon but a .45 caliber case doesn't fit. A 10mm cartridge drops in the barrel to the same depth as the 10mm marked barrels. A .40 S&W falls in until the back of the casing is flush-just as it does on the other 10mm barrels. By all appearances, it's a 10mm barrel. Why would it be marked .400?

    Because .40 Caliber and 10 mm are the same just different units of measurement.

    No, that's a necked-down .45 ACP. That cartridge doesn't come close to sliding into the chamber.

    Already sent them an email. Hoping they're shut down due to COVID and not just unresponsive.
