When I first got my Glock 48, I was able to switch the mag release from righty to lefty (tho not without scratching up my magwell a bit). I recently received my shield arms s15 mags (which are righty only) and decided to switch the mag release back to righty. After countless attempts and a lot more scratches to my magwell, this task just seems impossible; so I'd really appreciate any tips (especially what type of tool to use) on switching glock mag releases! Also, are the scratches to the magwell just a blemish or is it possible this can affect the functionality as well?
