Hi Tom, Thanks for the reply... so it would be safe to assume that just about any original un-altered .30 commercial Luger. using new current readily available .30 commercial ammo, would be originally equipped with too strong a spring... A newly manufactured spring would need to have either a change in the number of coils, or less wire dia. to make it softer....Length changes preload, but it doesn't change rate.. Did Mauser make any 7.65 Lugers during the 1930's and if so, was their recoil spring the same as commercials in the 20's & before?? I'm more interested in overall free length at this point then any other spec... Also, what did Mauser use for the 1970's reintroduction... I think a new Mauser replacement spring might tell us alot?? Maybe not... Best to all, til...lat'r...GT

Dear GT:

Every damned time I write more than just a few lines, my computer fouls-up and I loose it. Such was the case with my response to your questions.

Please call me and we'll discuss all of the secrets of making a Luger shoot. Particularly, we'll discuss the absolute need for proper recoil springs, the original DWM and Mauser specifications, modern Mauser Parabellum springs, etc..

I'd really like to work with you on developing a proper recoil spring, as nothing currently available on the market is adequate.
