I have a Mark II pistol manufactured in mid 1992. Somewhere along the line the paper user manual got lost and it is now my only pistol that I do not have a manual for. I've been looking on ebay and gunbroker and haven't yet come across one that is a 1992 manual. I'm wondering when Ruger made changes to the manuals they issued with new pistols in the early 1990's, i.e. will a 1991 or 1993 manual be identical to the manual that originally came with my 1992 Ruger Mark II? Thanks for your input.
