I see many times the comment about getting a "pre-lock" gun. What's the big deal? I understand the we all don't want "Big Brother" looking over our shoulder, but does anyone have a real reason for this type of statement? Yeah, a locked gun is a useless except as a hammer, but you don't have to use the lock. I have one gun with a lock. The only time I see it is when I take the grips off to clean. I've never taken the keys of of the package. (Ruger Flattop 50th Anniversary .357) This gun doesn't have a very good trigger feel, but I don't believe it's because it has a lock. Opinions?
