WTB - H&K P7, PSP or P7M8 (MT)

I am looking for a P7, either a standard P7 (some would call it a PSP) or a P7M8.

I want a functional using pistol to carry in the summer months so functionality and internals are what is important.

I would prefer to find one that I could purchase FTF, that means Wyoming or Montana but will consider any and all.

Thanks.
