I saw a Walther PPS with the same antler proof mark as with the other proof mark, not sure what it is, an angel marked "N" below it. Same as HK.
Are those just typical German marks or are they associated with HK. Their date codes are the same as HK also.
Also while I'm here, on my p2000 under the slide where the recoil spring goes into it's marked D6. Does anybody know what that means?
