Stove Piping

[Clay James]

I have a S/42 1936 P08 and I've had some issues with it stove piping. I think I have it narrowed down but here is what it's been doing. It will stove pipe sometimes several times per magazine. It also badly dents the brass. I've replaced all the springs and that didn't change. Tried many types of ammo including my reloads and some is better than others but it still does it.

What I think it could be is the magazine sitting too low. There is a larger gap between the magazine base and the frame than I normally see on Lugers. When I push the magazine up firmly while shooting it the brass ejects much further with almost no dent or none at all and so far it hasn't jammed that way. So, I ask the Luger experts, does this sound right? I may just put a spot of weld there and file it down until it sits higher. It's a shooter grade luger, so I'm not too concerned about a little weld as long as I get it to work correctly.
