@coleens_ I mean, this gun really looks like you want to do a "full disassembly" and "full restoration" into 'as close to factory new as possible'...
I'm just not shure how to do so, since most weapons proficiency classes and courses will merely demand a cleaning field-strip and proper gun etiquette and not a full-on disassembly.
So already disassembling the mag is out of scope.
#Funfact: the #P08 / #Luger has a dedicaded firearms safety question [in the §7 WaffG weapons proficiency exam] since it's one of the few guns that can have a round ready to fire without having a barrel attached, which makes it extra dangerous...
(Okay, not as dangerous as the "Type-94 "Baby"-Nambu, but you get the drift...)
