I may not try any more until I get another set of springs from Wolff...(see other thread)...

Hi,

Where did you get your O.A.L. figure, as it should mirror an original Japanese round, somewhat.

Nambus are not as touchy as Lugers when it comes to O.A.L., thank the slightly straighter grip angle for that.

Good luck, and do replace your springs with a fresh set of Wollf springs, as the metal in the Japanese springs is inferior.
