Don and Doubs,
Don -I believe you are right regarding the Remington ammo but I still wonder why, if that is the case, what's wrong with their ammo. I also checked the Ejector and can't find anything broken or excessively worn (see pic). However, I don't know what a perfect Ejector would look like. Doubs - The recoil on this P08 is strong so I don't think that's the problem.
Again, I really appreciate your inputs.
