The slide lock is also the takedown pin, and to get leverage some folks rotate the slide lock, which scratches the fram.
When you own a 1911 (notice I didn't say if) the new owner stands a good chance to demonstrate his lack of experience when reassembling after cleaning.
What happens is the slide stop requires a considerable force applied to overcome the resistance of the safety/slide stop plunger. Rather than using a tool to push the plunger back into the tube the rookie simply applies more force. This causes the slide stop to slip off the plunger and rotate around the barrel lug pin scratching a semi-circle "Scarlet Letter"
on the receiver and if really overdone, the slide.
