I was looking through the Gehmann website and saw the lockable rear sights(595). I'm just wondering is it good, and also, has anyone used it before and found it useful?

I have two of the sights you're talking about. The locking thing really isn't important, in my opinion. Especially for shooting outdoors where you will want to keep up with wind changes, etc, it's not important. Not to mention, the clicks are definate and they don't move very easily (good for clicking on purpose, they won't move by accident or you will notice it). All in all, it is a decent sight. Nothing special, but nothing bad by any means. It's a pretty compact sight, which is nice. Hope this helps!
