I am not familiar with that one. I know my Father learned to field strip his bring back Luger by himself. I bought one around 1988 then sold it around 4 years later. I never did figure out how to field strip it mostly because it was not shot very much.
One of the most difficult ones for me is the Ruger standard model .22 or target model for that matter.
Also the Astra 400 and 600. It is easy to move the slide assembly off the frame but to field strip it is fairly hard simply because the spring is so strong.
On a Luger, you push back the barrel with you left hand and turn a lever right under the barrel at the gun’s left side. Then you’re home free.
Bought a Luger in 1961 from a newspaper ad for $40 and it was delivered at my home through the mail.
