I have a Colt M1917 revolver and having trouble finding full moon clips for it. I purchased some on line from a reputable company and they don't work. Once installed I can't close the camber. If I force it closed the camber won't turn (too tight, no clearance). The company's webb site says these clips will work with Colt/ S&W model 1917 revolvers, but I went to the webb site of the manufacture of the clips ( Wilson Combat) they only list them for S&W. I have veiwed videos on utube of people using full moon clips for my specific gun (M1917 Colt 45) with no problems. So my question is what I'm I doing wrong? Or where can I find clips that will work in my gun?
