Did you check that link I posted to make sure you're looking in the correct place? What caliber is your P99? What importer marking is listed on the front right of the slide--such as Interarms, Carl Walther USA LLC, Walther USA LLC, or Smith & Wesson?[b said:Quote[/b] (Scrogman @ May 19 2005,5:44)]Mine really doesn't have a date code. I have looked everywhere. I know it is an older frame because of the hump in the triggerguard and that stupid old walther accessory rail. There isn't any wear on the sides or the bottom of the frame around where the stamp should be. Where is my date code?
