and a few more....
Thou shalt never ever ever pull thy firearm unless thou intendest to use it.
Thou shalt never joke about using thy firearm: thy firearm is for thy protection, and thou shalt treat it with the respect it deserves.
Thou shalt not twirl thy revolver upon thy finger, nor shalt thou twirl thy pistol: remember, man, that thou art NOT James Arness and thy life is NOT Gunsmoke, nor art thou Mel Gibson or James Garner in Maverick. Thou art thyself, thou art not, nor shall thou becomest, a movie character.
Thou shalt always always ALWAYS wear thine ear protection when shooting thy firearms, whether thou huntest, or shootest trap and skeet, or the holy target practice; thy hearing is important, and thou shalt want to HEAR the trumpet on Judgment Day, not to mention thy children's laughter and thy spouse's endearments.
Thou shalt never fire a .357 magnum round in a .38 special revolver; thou shalt remember that guns are but metal, and if thou puttest in a round not intended for thy firearm in its chamber and pullest the trigger, thy firearm may blow up in thy stupid face. A .38 round thou mayest shoot from a .357, yea, even a .38 +P may thou shoot, both in a .38 special and in a .357, but thou shalt not shoot a .357 magnum in thy .38 special lest thou find thyself unexpectedly in the emergency room or, worse, meeting thy maker and being asked why thou forgottest this rule.
Amen.
