Breech Block Failure 1916/1920 Erfurt

Thank you G.T. your help has been much appreciated. I will try the gauge first then a test shot and check the case/primer. If no go it will be on the way to you. I have a couple of P-38's and old Hi-Power and another Luger I have never checked so the $30.00 gauge will get some other use.

Hi Allen, at least with the forum help, you have a lot more info than when you started!

.... As for the gauges, once you have the "NO GO" you can use it as a base guide dimensionally and put scotch tape on the back of a regular empty and make your own "GO" gauge! I've done it many times, and even made incremental sets to see just where I was at when re-barreling?.. I pay a'lot of attention to where the toggle knob is in relation to the receiver rail when using gauges, both "GO" & "NO GO" on closing. You'll get a feel for the exactly right head spacing, more importantly, you'll have a baseline if ever a problem should arise... If possible, I like the action to close tightly on the "GO" .... seems to work out fine in the overall picture.... best to you Allen, til....lat'r.....GT...
