Most of my pistols are revolvers. Now it's not unusual to get a brand new revolver that's "tight". I almost sent in my 642 because the cylinder was tight to open however after shooting around at least 400 rounds thru it and cleaning it between range visits, the tightness has worked itself out. My advice is DO NOT put a tool such as pliers or do anything to the ejector rod if you do not know what you are doing. if you can't turn the rod by hand then it's tight. if you are not fully happy with it then give S&W customer service a phone call and they will correct it...

This is why we inspect firearms before filling out the 4473.
