I bought one of the P80 kits this year, but cannot get a definitive answer about having to put a serial number, how to get it, etc..and can't seem to find jack S$$t on the subject. So, I'm truly afraid to even take it to the range. I am willing to cut up the frame, lesson learned, but can I use the upper slide, barrel, etc. on a G23 frame? The upper is a .357 Sig that will go on a .40 Cal G23 frame?
Hopefully someone here will be knowledgeable on the subject? I'd hate to cut the frame up, because the thing is laser accurate, but a jail cell is not really a great place for building more guns. I hear they never have happy hour, either.

Thanks ahead,
