Be careful with that. IIRC the decockers on those were unreliable and the pistol might discharge on using the decocker. A friend had one thus that his father had ended up with after WWII. His dad wasn’t anywhere near infantry combat, he was a PBY pilot scouting for German submarines, but somehow he ended up with a P38.
The decocker is one of the main reasons I like to carry it, and I heard about the issues. It always worked for me, of course I’ll keep saying that until I hit it and put a hole through my kitchen wall
Air bases were places were front line troops often traded their trophies. I had an uncle how flew R4D (C-47/DC-3 navy variant) in the Marines. He had accumulated quite a collection of Japanese war trophies. Much of it did not make it home due to a continuous poker game on the troopship back home.
