I think you are.
Not EVERY slide stop from every maker WILL readily / easily go straight in. I fit all of mine that are difficult to a 1911 whether it already has the scratch or not. Not to avoid making the scratch, I don't give a *hoot (*a cautiously selected word) about the scratch, but just to make assembling easier.
All of this scratch whining and making disparaging remarks about it makes me wonder if peeps go to a plastic bushing wrench to avoid a scratch? Put in TORX, or allen screws to avoid scratching the grips with a screwdriver? Lining their holster with unborn calf to minimize finish wear? Maybe just leaving it in the safe to keep it pristine?
Egads... in guitar player fandom we have a saying "shaddup and play yer guitar" Maybe less obsessing and more shooting is in order?
