Recently picked up a pair of Smith & Wesson 1911 E series pistols. While reviewing which gun to take home-only one at the time-the dealer noticed serial numbers of two the guns where sequential. Not wanting to split the pair...I bought the second for my wife. Now the questions: 1-Do they have any benefit or added value if they are not shot? 2-If you planned on not shooting them, would you clean them? They are still in packing grease... Your opinion is appreciated.
