The S & W model 48 revolver in .22 magnum seems to have a history of the cylinders being too tight. For example in my model 48 If the cylinders are clean and the revolver fires the 6 rounds, they are very difficult to extract without the use of a small rubber mallet. I took my revolver to a local gunsmith and he worked on the cylinder and said he could fire about three rounds (of 6 each) before extraction became difficult again. Before taking this revolver to my gunsmith I called Smith and Wesson and they said they could only help if I furnished them with a new cylinder, like I have one laying around! I'm hoping some of my THR brothers can provide some direction that would enable this fine model of a handgun to be really proficient. Thanks in advance!
