Spring Replacement

Terry Tiell · 07-07-2012, 01:49 PM

I know when I replaced my main spring the one that came out was almost a full 2 inches shorter then the new one that I installed.

Ray, I remember when Hugh and I were first working up loads I found two powders I really liked with a 124 gr FMJ. Unique for standard 4" Barrelled Lugers and for finicky Artillerys a good bit of Blue Dot could make those long barrelled Lugers boom and rock and roll,

Thanks to each and everyone of you for your inputs; you fellas and the rest of the guys on this forum are the nicest, most helpful people I have ever had the good fortune to communicate with.

I have seen Lugers in the past that were locked open for years and thought this would have to have an effect on the mainspring. I have fired the 9mm with Winchester white-box and the 7.65 with Fiocchi and Geco and there were no malfunctions of any kind. Both of my 29/70's have 6" barrels.

I installed a Wolff mainspring(std. weight) in my 1921 DWM, and it is performing well. I also installed the firing pin spring that came with the mainspring. I also reload and this is what I have been using with success:

(1) 9mm 115gr FMJ with Unique, and Power Pistol

(2) 30 Luger Red Dot and Bullseye. The BE load is a factory matching/replacement load according to my 1970 Lymans Reloading manual.

I have located a 93gr LRN bullet that is for the 30 Luger brass. It is working out very well for me in my Luger.

When I pulled the original main spring out and did a side by side comparison of it to the new 38lb spring the old one was almost 2 inches shorter in length and it was kinked in several places. I can post a pic if you would like.

Yes, please...I have three Wolff mainsprings sitting on my bench [36, 38, 40#] and they are all right around 3 1/2" long...Your mainspring would be 1 1/2" compared to those...I have to wonder if it would even cycle properly...(But it would be a breeze to install)...
