I have a Colt Commander that's been converted from 38 Super to 10mm. There are no caliber markings on the gun except for the barrel (it's an MKIV which at one point had no caliber markings on the slide). Barrel is a Kart which is obviously marked 10mm. Colt never factory manufactured a Commander in 10mm and wondered if this would be a legal problem if I ever had to use it to save my life or others. Any law experts out there that can tell me (I've heard many theories how lawyers can make this an issue, but is it realistically a liability?). I'm in CA (I know!).
