My P08 model 42 is suffering from jams :(

[Johnny C. Kitchens]

Try another magazine, for sure. When I got my first Luger, a byf 42, I was told by the "experts" to get the ammo with the heaviest bullets, and full metal jackets. I did, but the gun was a single shot, occasionally allowing me to fire two shots before jamming. Then I read an article by Michael Reese suggesting a new magazine. I bought one as well as some other ammo, including a box with a very light soft point. I actually went thru several magazines before a jam occured. Then I got up the nerve to take it apart and I cleaned out all sorts of crud, and I used a good modern lubricant on the moving parts. Even today the gun shoots just about anything I can put thru with no jams. One exception, Corbin ammo. Seems to have trouble with it. I tried six other kinds last time and they all worked 100%. I would never call the Luger's action delicate...
