PineKnot has given a very good post on this subject, worthy of keeping in rememberance. I will however, disagree with him slightly on one point, ie triggers. Many guns have a light spring which keeps the trigger in contact with the sear. If this be the case when the locks are removed the trigger blade will be pushed up into a position where they will interfere with the sear being seated & the triggers will need to be pushed "Forward" as the lock is positioned. This will not indicate any problem with the gun.
