So while I was fine tuning some reproduction grips on my surplus Luger, it just so happened that I found some needle nose pliers around and played with it.
Before I knew it, I had the main spring out and back in.
You even have one hand free to get the retainer thingy out and back in etc. etc.
What a nice exercise since I am going to order the Wolf spring set soon for a tune up.
Do it carefully and there will be no traces on the parts.
I made a short video but I cannot upload that here I found out.
Maybe the pictures will do to give you the idea?
Let me know what you guys think.
