So, its three inch, round butt, has a nice trigger job, stainless, seven spead loaders, two extra sets of grips and 3 boxes of ammo for $450. The down side is its got the internal lock and he lost the key. I've heard of these things locking up while shooting and I've also seen a video (on youtube) how to remove a lock from a model 640. Would there be legal issues if I removed the lock? All my guns are kept in a safe anyways. What do you folks think about this deal? Thanks for any feedback, Rick
