I am new here and am not trying to stir the pot but I don't understand the "big" deal about the internal locks on the new S&W handguns. I own a mod. 637 38 spl+p and I have had no problems with it. I have never locked it and I don't carry the keys. They stay with the original box and stuff in storage. To me they are as safe as you are. Am I missing something about the locks or is it just something nobody wants because the are a waste?
