I bought a used S&W 40E today. Really good shape and a good price. I shot 100 rds through it and it shot very well. It seems there is a love hate relationship around about this gun, mostly what I have read that people love to hate it. Does anyone own one that can give me insight about what problems might occure and how to fix them. The one I got may be the exception to the rule. It shot a very good group @ 25 yds.
