I'm one of the few who only have 2 Glocks. The G23 and the G43x. I have the conversion barrel for the 23 + the 19 mags making it a sweet shooting 9mm. Two guns in one! As for the 43x well I'm waiting on my shipped! 15 round mags from Shieldarms but the skinny little girl sure can shoot the sh!t out of the 10 round stock mags.
