I just purchased my first revolver, a used S&W Model 65. The first thing on my list was a good cleaning. After a routine cleaning however it still had a bit of a gritty trigger pull. So using a couple online guides and an exploded view I proceeded to disassemble the fire control group. I've assembled a couple AR-15s and detail stripped my Glock so I'm pretty careful when it comes to these things. I hit a couple snags but was able to figure it all out, clean it and put it back together. The trigger pull is now silky smooth but there's a new problem now. Previously, before I disassembled it, when I pulled the hammer back partly and moved the cylinder you heard a very satisfying click for each chamber. Now there's nothing. If I pull the hammer back partly the cylinder spins soundlessly. All other functions appear to be right. I haven't fired it yet so I can't 100% confirm that but I'm fairly sure. Should I be worried? I did oil the internal parts and then wiped them dry which should have left them with a thin sheen of oil for protection. Could that be causing this? EDIT: Took it apart again to see check the function and I guess it's the hand that would make the audible click when the cylinder is rotated. Still don't know why it doesn't make the click anymore. I did notice though if I pull the trigger "slightly" to allow the cylinder to rotate it does make the click, but not when I pull the hammer back slightly. What the heck did I do to it?
