I only own 1911s and DA revolvers. I don't have any doubles of exactly the same brand and model but I have multiple 1911s and DA revolvers so the manuals of arms are the same. It keeps things simple when going from my duty gun to off duty, etc.
"If violent crime is to be curbed, it is only the intended victim who can do it. The felon does not fear the police, and he fears neither judge or jury. Therefore what he must be taught to fear is his victim." - LtCol Jeff Cooper
