Like this? Safety on, pull the trigger, take the safety off and don’t pull the trigger again and it fires.
Hmm. Could there be a problem with German lubricants? Besides guns (and other things), I collect Zeiss cameras. They used a funky green lubricant, that over many years has turned into an adhesive. And a Contaflex camera, unlike a gun, is almost impossible to disassemble for cleaning. (You can try it, but you'll go insane.) You can try a shot of carbon tetrachloride, but if that doesn't work, the camera has to be relegated to display only. Hopefully this works better on the guns.When you receive your Luger clean it. Get all the oil and compacted grease out of the firing mechanism. I have purchased a couple of old pistols where the mechanism was glued into place by old, oxidized oils and greases.
