I just checked my M13 and it is W. Germany as well 73th serial, I have never checked the date.
The early PSP had two models, different mag latch.
I got a set of EXC walnut grips for it this spring from GRIPS4U out of the states and they are fully as good as Nill.
The wood grain is nicer than 2 sets of Nill I have seen.
They where out of stock for a couple years, just make a run and that is it for a while, low demand they say, good people it seemed like.
The M10 mags work great in a M13.
Only thing I have not done is shoot lead at steel with it as I wonder is the lead may plug the gas port up?
