I'm a little late seeing this post, but I will jump in. I have a '76 P64 and it is fun to shoot. Retro is right though, the DA pull is a bit heavy (I have read up to 29lbs) but I choose to think of it as a safety.
The first time I took mine to the range I put 200 rounds through it and my hand swelled up from the recoil. The solution was to shoot about 50rds max per outing. For me it is quite accurate and very reliable - no jams, FTF etc.
It is not an acquired taste. The DA pull, recoil, and round (9mmM) will make some just shrug and ask why bother.
For those who know the CZ82, think of the P64 as its more concealable, less refined cousin.
