Stu you are correct there are a loft guns that have nicks fetted reg on .
However both mine in use are not fettled by nick ,One s done by myself and the other was done by my good pal Pete dutton
I have 5 spare regs all done by myself or Pete I do have a reg done by nick but ts not on a gun
Nick alters the valve in the reg and changes the firing valve seal to delrin none of which Walther have taken up
Both my walthers have the firing valve seal mods done as well
