1902 American Eagle

The head space won't have any significant effect on your problem, JMHO.

It IS the barrel.

I just finished building a 12" carbine clone in .30 and a 16" bbld. 9mm.
The 12" bbl is significantly heavier than the original barrel as is the 16" , both require a lightened mainspring in a P08 to work. I seriously doubt you can make that one work by itself.

The 1900 based carbines had an auxillary spring in the forearm to help close the toggle after firing.

As to the white markings, the white is added for visibility by the owners. The only filled in markings on an original luger is the "Gesichert" or safe marking; yours does not have it, it has the polished area under the safety lever.

I realize that you are a handloader and have been experimenting with different loads in this Luger, but I have to ask if you have tried factory ammo that frequently has the case shoulder set back farther than many sizing dies will set it back, without "tuning" of the sizing die. The 7.65P round headspaces on the case shoulder and not the case mouth. I am having a hard time understanding how shortening the OAL of the brass is helping you with RTB problems.

Thanks for your input and info - I'll try to get a decent pic of the inside of the chamber as there is a definite "ridge" which appears to be located where it would meet the mouth of the casing and the "trimmed cases" do seat deeper in the chamber. I have tried this chamber fit procedure using casings from original DWMs to new Starline brass and some older Winchester rounds I scored . I really appreciate having so many knowledgeable firearm enthusiasts making suggestions as on my pension I can't afford to send it off to a reputable gunsmith.
Like Arnold says - "I'll be back!"
Thanks again Bruce
