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.
“Never give in. Never give in. Never, never, never, never—in nothing, great or small, large or petty—never give in, except to convictions of honour and good sense. Never yield to force. Never yield to the apparently overwhelming might of the enemy.”
