Al,
There are over 30 different variations with grip safeties. If you add the extremely rare ones to that, it's over 40. Most of these had 4 3/4" 30 cal. barrels. Fewer had 4" 9mm barrels and fewer still, maybe 3 different variations... (Navies) had 6" 9mm barrels, and have a 2 position adjustable rear sight.
That's a pretty big ballpark. We definitely need more info to help you.
