I have ordered the "no go gauge" and will start there. The barrel was never changed out as noted all matching serial numbers up to the point of the breech block failure other than possibly the firing pin which I did not check for matching. I did note the firing pin is fluted which indicates the pin itself may have been changed at some point. The theory on the rim size is intriguing as I have an old "Star" 9mm that jams on the Blazer Brass and works flawless on Remington. I have 2 uneducated guesses on what may have caused the problem if that is even a possibility. I came across a factory cartridge one time where the bullet was set probably 1/3 deeper than the rest however, that should not have affected headspace? Needless to say I did not fire the round out of the Glock at the time and I disposed of the round. Is it possible as "Karl" suggested that for whatever reason the mechanism did not go into full battery? If this is the case could the pistol still fire and that be the cause of the problem? There is really not anything else I can think of as the rest of the parts are in good shape. I shoot a WWI DWM all matching that I have however, only on occasion and all I have ever used is Remington ammo with no problems.
