I have just purchased a NIB BA date code USP Compact .40. It's a made in Germany gun. I have talked with a couple members here about the conversion and parts. Does anyone know if you can buy the var 1 kit for it? Being as it's a new well 24 round old gun I would like to have new or close to new parts. I was told in a different thread to try HK. But I read someplace that HK wouldn't sell them to the public. I know I have the new style firing pin block but I can't find a different part number for the old style and new style spring. A member here gave me a list of parts to get but buying them seprate is going to cost quite a bit.
