I picked up my Sig 1911 Tac Ops. Brand new. I have a couple of questions: 1) Look at picture #2. Is the thumb safety suppose to mar the frame that badly? There was no marring when I got it, but after say 5-10 uses of the thumb safety, the frame looks like that. Is that normal? 2) It seems the thumb safety has two "stages." Not sure how to describe it, but the safety would get a "click" at half way (see pic 3), another push will engage it fully (pic 4). However, the trigger cannot be pulled while the thumb safety is at the half way click. Any help would be appreciated. Thank you.
