I have a 717 from maybe 35 yrs ago, still works great, no leak and accurate! I broke a plastics "receiver" end cap when I took it apart to tune the trigger and lube maybe 20 yrs ago, but never bothered to replace it, probably parts not available anymore! I still have the part order form came with the pistol, unbelievable cheap prices! Maybe I should use the order form to order parts and see if they honor the price!
