Multiple guns of the same make, type, caliber, finish, etc? Sure...it's just another symptom of the affliction. Later on you'll be looking for different guns that go with the decor in your house. In your case, I'd go with another 915...easier and probably less costly than trading it off and trying to get into two new guns. Then again if you like the .45 there's the Denzel Washington Training Day 4506 option, or the Bruce Willis Last Man Standing 1911 option. So don't limit yourself...you may find that having just one set of paired up pistols isn't going to be enough.
