Prewar commercial C96 fires only is I hold safety down

[f4wso]

I have a prewar commercial #83xxx so I believe made in 1912/13. It has the proper second type safety and trigger as best I can tell. Function fine except in order to get it to fire you need to hold down the safety while pulling the trigger - not safe. It feels like it goes into the detent ok and will not fire if I pull the trigger and then hold down the safety.


I replaced the mainspring and recoil spring and no change.


Any idea of how to fix this problem? If not, I'll ask the age-old question. Any gunsmithes out there that work on Mausers (C96 or HsC)?
