ViggoG is referring to his 1906 AE Luger, one of the exempted ones with a correct combination.
And unless you have a gun that is "exempted", then don't buy a stock for your Luger.
It could just cause problems.
I have an artillery Luger and just because I have an arty, and I went to a range with a 4 inch Luger, I could be in deep trouble if my arty wasn't with me, or if I used the stock on my 4 inch <img border="0" title="" alt="[Eek!]" src="eek.gif" />
Just not worth it.
Anyway, sorry about all the negativity, so just be careful out there and
Welcome!
