Tony,

Glad you got the takedown lever tightened up with the spring that G.T. provided.

The Luger is a very interesting, and perhaps unique mechanism. As mentioned, it's design is very dependent upon correct balance of forces (including recoil against your grip) for proper functioning.

You will probably not encounter another firearm design and implementation that is so precision in nature. There is a reason that many parts on a military Luger pistol were numbered. Much of the precision was accomplished with hand fitting.

This is unlike more modern firearm designs. They have quite a bit more tolerance to slight irregularities. In fact, this ability to function with less precision in the mechanism is a significant advantage on the battlefield.
