It's not completely finished. I still need to get some sandpaper and an exacto to finish shaping, but it's almost done. Mags fit nice and feed perfectly. Lots of dremeling and filing but worth it. Here it is next to the 45 to get a comparison. First with the fullsize mag with the sleeve to make it normal sized for range and also as my backup mag. Next with the SubCompact mag with pearce extension for daily carry. (Still 10 rounds) And for days when it's Tshirt and shorts I will have a mag without the extension for least footprint.
