My brother bought me a wood burner for Christmas. When you're tired of the internet at night you should not play with wood burners and plastic guns. I basically wanted to see if I could do it. After watching tons of videos online it didn't look that hard. Maybe I should have had somebody else do it it. Haha. I sanded off the finger grooves of my 34 then sanded the grip side flat. Also sanded flat the little Ridge underneath the left thumb. Then I undercut the mag release button just a touch. It feels like 100grit sandpaper. Not as harsh as i imagined which is good..
