Conversion 7.65 mm to 9 mm

Another option you have, is the one that I chose. I own a 1921 DWM P08 in 30 Luger. Over a period of time I located a rebarreled 1939 receiver/barrel extension in 9mm. For a while, I used my original toggle train with both uppers, but recently purchased a complete Erfurt toggle train in excellent condition. I had to headspace the new 5in. bbl. but now I am able to switch back and forth between 30 Luger and 9mm. I have installed a mainspring that works for both calibers, and the same mags work also.

I am a reloader, so firing either caliber is not a big difference price wise. I just enjoy being able to shoot either caliber. My choice.

By having a complete upper, one does not have to risk a barrel change, and possible damage to the components. Just one more option for you to consider.
