I shoot 5.7 grs of Unique behind a 124 FMJ but only in guns that have a spring tension close to factory specs.</strong></font><hr /></blockquote><font size="2" face="Verdana,Tahoma,Arial,Helvetica,Geneva">Hey Thor:

Thanks a million for your response!!

You raise some interesting points that show your years of practical experience with these fine pistols.

My questions to you, and they are very technical ones:

What were the original factory specs on the coil recoil springs of the early DWM (100mm barrel)pistols?

What were they on the later production Mauser P-08s?

The Interarms' Mausers produced in the '70s had yet different weight springs, and quite heavy ones at that.

Are these actual weights currently available
(from Wolff for instance)?

By changing springs, can one expect an original lightly springed Luger to function properly with the hotter loads? For instance, if you were to develope a maximum load for a Luger and tailor a proper weight spring to handle the load, would this "work"?

Thanks

Bob
