Yes, the recoil spring in my byf 41 does have 20.4 coils but it is drawn from obviously smaller diameter wire than my DWM 1916. Harry E. Jones in his book "Luger Variations", Volume 1, page 30, has a thorough analysis of the recoil springs from all of the various Luger models. This analysis was done with the help of a Baldwin Tate Load Indicator and a Reicherter Elasticometer, so the results "should" be credible. Here are some highlights: Model Wire Dia. Turns Length Poundage 1906 Brazilian .060 15 2.625 65 1908 (P-08) .058 17 3.20 56-57 1923 7.65 & 9mm .060 17.25 3.15 60 1934 Mauser .058 20.4 3.50 58.2 As you can see, there was no "real" increase in spring poundage over the years, per Jones' analysis, anyway. Also, WWII German machine gun ammo was uniformly made with lacquered steel cases. These would jam in the Luger. Special brass cased pistol ammo was made for P-08 usage, as I have seen many original boxes of WWII ammo so marked. One thing that I'm sure we can all agree on is that when you open up a Luger, you really don't know just what type of spring you will find! Also, no doubt, the actual quality of the springs used must have gone down hill during war time production. I might add, that the 9mm Interarms Parabellum spring you sold me several years ago works perfectly in my 1917 DWM (with either light target loads or my WWI German military clone handloads) and it is quite a bit "heavier" than my original byf 41 recoil spring!!!!! Go figure. Sieger Last edited by Sieger; 08-06-2011 at 07:31 PM. |
