I knew two officers issued a model P7 (forget exactly which). They fought tooth and nail to keep them when others upgraded to newer HKs. They love them and sadly I never got a chance to try them out.
both of these guns were police trade-ins, I bought the psp from 2a sales a couple years back when they were everywhere. The m13 is a American police trade-in I found on gunbroker, it came with his safariland holster and mag pouch. tons of holster wear so I had it refinished.
I love them but just don't seem to pull the trigger due to price. I'm going to have to be in the right gun store, at the right time, with the right american express card, and will probably do like a friend of mine did when confronted by the right 380.
I just checked gunbroker and wow are prices up there! I remember contemplating 2 years ago about selling the psp because I liked the m13 better and could just get another one anytime I wanted to. I'm definitely glad I kept it
