Mine was $550 w 2 mags in '85. +or- 2500 rounds through it. 2 years in sunny Florida in a Milt Sparks Summer Special. I've meant to check out some of his other models that keep a bit more leather between skin & blue steel. FWIW...I've had only 2 "jams" in 2500 shots. My 1st shot with it ever; a 2-hand hold and the off-hand thumb must have depressed the ambi mag release enough to drop the mag 1/4". Of course the next round failed to feed. I made a mental note not to do THAT again and I never have. It also had one "stovepipe" shooting lead reloads during a class/drill and that also never, ever happened again. Never any other problem at all. The first time my wife tried it, she put a round 3" from the X @ 7 yrds. The next 5-shot string was a slightly ragged single hole 1" from the X. The best P7 quote I ever heard came from someone here on ARFcom, (credits to whoever it was) ... "Holy Sh!t, what were you thinking? Getting a good deal by selling a P7 has got to be like winning the special olympics! Even if you win, you're still retarded!" Glad you found another.
Stay safe
