So I'm debating on picking up a Hi Power 9mm, serial number puts it at 1987 range. It's supposed to Made in Belgium, looks to have a parkerized finish, it has the ring hammer and only a single safety lever instead ambidextrous. Has the FN markings on the left side of the slide. I do not know yet if it's "Made in Belgium, Assembled in Portugal" or just "Made in Belgium" stamped. Any advice good or bad is appreciated and what is the approximate value? Thank you.
