And having "Folding Glock" as your username shows no attempt in even TRYING to conceal the astroturf....
I actually think the Full Conceal M1 might have some merit. It's basically a 19 frame chopped down to 26 size, with the Full Conceal extra magazine to swing down as an extra. It's fully functional as-is, with extra ammo on board. Other forum members have chopped their 19's down to 26 grip length, and been satisfied.
