My dad recently passed away and I now have his his old Colt Detective Special, issued to him when he was a NYC Detective. I researched the serial #...710632, and it appears it was issued to him, or he purchased it in 1958...I think he made detective sometime between 1956 and 1958..nickel finish and pretty clean with wood grips..seems I remember white (pearl) grips on the gun when I was a kid but couldn't find them. It shoots fine, just had it on the range this week, much more accurate at 35-45 ft than I expected..I put 4 of 6 shots into the target head and the other two right on the fringes..anybody have any idea what this firearm is worth, not that I would sell it ?? Thanks.. Chuck J.
