The Ruby pistols are al pretty different - that is what led to their bad reputation. They were made by a large number of small companies, many with a lot of hand made parts, and little or no interchangability. IF you find another Ruby made by the same maker as yours, you might find parts that fit...if not, it's a real crap shoot. You should chek the sticky on the Ruby pistols at the top of this forum...lots of good stuff there.Hi I also have a Ruby, an old 1915, needs some work, know where you can get parts, sprigs etc? I have seen some relatively unused 1915's and liked them a lot!
