Perhaps you have noticed the warning from SIGARMS which insists that the hammer on the Sig must always be dropped by the decocking device and never by the thumb. This is curious in view of the fact that for many years the Walther people always recommended that the weapon be decocked with the thumb and not with the hammer dropper. This is still more evidence of a world in which we are to depend on machinery rather than upon ourselves. Dropping the hammer with a decocker is usually safe. (Just be sure the weapon is pointed in a safe direction when you do it.) Lowering the hammer with the thumb is always safe if the operator is safe. Of course, if you must assume that the operator is inept, then decocking with the thumb is not safe.

We dinosaurs prefer to put our trust in our own abilities rather than in any reliability of a mechanism which can fail. - Jeff Cooper
