SOLD......please close/delete OEM 70 magazine that works just fine, OEM 70 style grips w/screw, three hard to find springs (trigger, sear & extractor) and a Harrington Products improved firing pin & related parts. Visit www.harringtonproducts.com for info & installation on their CZ related upgraded parts. I had this upgrade in my 70 and it functioned perfectly. I removed it and reinstalled the OEM pin before I traded it. Everything here is compatible with the model 50, as well. I have all receipts and everything totaled to $130, but I'm selling all for $50 shipped to lower US 48 only. Pay Pal or money order is fine. Thanks for looking!
