If you own a 1911 pistol you are well aware of the idiot scratch from reinstalling the leaver into the firearm to hold the slide in place. I came up with this idea and it works great just tare down pistol then take a buiessness card lay over area where the leaver goes into firearm mark where hole is and where the part goes into the square area next to grip. Cut them out just enough to expose areas where holes are no more. When you reassemble firearm lay the card in place insert the leaver and push in and up at same time but the card is protecting the case of firearm. Once it is snapped in place just slide the card out and no scratch or chance of scratch.
