shooter john: i know the stippling looks a little funky, i was trying to make the pattern a little more organic. i used a large round tip. after final finishing, the grip works exactly as intended. you actually get a better grip when your hand is wet.
Thumbtack: to chop the grip i removed the slide and inserted a 23 mag, i then removed material with a craft knife and sanding block ( to keep things level) from the front part of the grip. I simply did that until the mag would lock in just right. A quick note, while not necessary i did swap the followers from the 22 mags to the 23 mags. the 23 mag followers have slightly less material where they contact the slide stop. the swap gives a little more empty mag drop force.
