So I have a Colt Det Spcl from 1974.It belonged to a girl I worked with who signed it and a couple of handguns over to me when she took an early retirement.At the time she could only put her service gun on her NYC permit for the first year.She took a couple back as she was able to put them on her permit.She passed away before she took back the Colt.I tried to give it to her brother who was with NYPD at the time,but he didnt want it.So I put it back in the safe and never used it.I've had it for about 12 yrs.I took it out to look at it today and it was very "stiff" so I took it apart to clean it and was blown away by how much gunk was in the works.It belonged to her father who gave it to her in '83 when she went in to the academy.Its obvious he never cleaned it and neither did she.Seems to operate well now,I've never shot it,but as soon as the weather gets better here I'll take it down the road and give it a run.
Easy way to deep clean a revolver. Soak it in Ed's Red for a few days then blow it out with an air compressor. (Remover the grips before soaking). If that doesn't work, repeat the process. If it still doesn't work, there is something terribly wrong with that revolver.
