I took my new (to me) G39 to the range today and ran 100+ rounds thru it. This thing is amazing! I haven't fired my GAP's in a while and I forgot how accurate they are! I shot it better than I do my G42 (my current EDC). I fired mostly Lawman 200gr and I also ran some Federal 230gr HSTs and Speer 200gr Gold Dots. The Gold Dots felt like I was shooting a 9mm. I have magazines both with and without Pierce extensions and I actually prefer the magazines without the extensions. One round of fire with the extensions pinched my pinky. I have small hands and have no problem firing the G39 without them. Once I get the holsters I ordered for it, it will be my new EDC whenever possible. (Sometimes, the minuscule size of the G42 is necessary for concealment with certain outfits). I did also order an extended, ported LONE WOLF barrel for it. It was on closeout and thought it would be fun to try.
