I recently purchased a Ruger GP-100 in 38 Cal. Serial #176-25948.Can anyone tell me the year this gun was manufactured and how I can get an owners manual. Since it was a used revolver there was only a spattering of paperwork with the gun.
Ruger did make a 38 spec. GP-100. Mine is a 4" fixed site GP. They also made a 3" with adjustable and fixed sites in 38spec. Those may have been a dealer exclusive. Mine was a short lived regular production model that dates to around 1999-2000.
