Jerry,
You said "Mauser improvements" ; I just wondered what you thought they were; since I don't "collect" Mauser lugers, I thought I might learn something. You did remind me about the extractor difference. The hump I never thought of as an improvement - but it is.
In other cases they were not improvements by Mauser.
Rich is correct, I just don't like general statements or repetition of "common" knowledge.
Where the info is available, I like to know what/where it is.
I believe a 1916 DWM luger can be an excellent choice for a shooter.
I see extractors and ejectors as expendable and replaceable parts in a shooter; along with springs and grips. JMO. This does not mean that a Mauser luger is not a good choice, but it is often a more expensive choice- due to the "Nazi" and/or WWII mystique that seems to command a premium.
Norm, thanks for your comment- nice to know I'm not the only "one".
