Not sure how many of you fallow nutnfancy on youtube, but I'm looking to do his recomended sanding of the sharp edges on the mag release to my g23. The sharp edges and corners bug me and 400grit sandpaper seems like an easy enough solution. My question for those who have done it is: is it best to remove the piece from the frame to work on it, or did you just do it in place. I'm kinda torn because I'm not really excited about detail stripping the frame but at the same time I don't really want to mark up my frame if I get sloppy with the sand paper either. Any advice? People recomending I buy this that or the other part and simply swap mag releases need not reply- I'm aware of those possiblities and am not interested.
