I've done some work on revolvers before. But this charter arms - it does take some notes from a smith and Wesson but how do I go about getting the cylinder stop to stay down just a tad longer ? I have one where it pops up so early it goes back into the notch it left and prevents the cylinder from rotating. I replaced it with a new one which solved the problem but it pops back up just after the notch has left alignment with the cylinder stop so I fear any amount of where could result in my original problem again.
