You know how you can never find the Kel-Tec spare mag holder that goes on the buttstock of the gun ?
Well I found that if you buy 2-Blackhawk 430900BK Black Pistol Tactical Magazine Pouch With Molded Flaps , that you can mount them on the side of the foregrip by just drilling 2 small holes.
First you remove the foregrip like you were installing the picatinny rail , then on the side closest too the breech you find the waffle pattern square that is on the bottom row the second square back from the breech and drill a 7/32nds hole in the dead center , put the upper screw from the pouch in that hole and line up the lower hole to match (its about the 5th square back) and screw it down.
Adding 1 mag pouch will increase the width of your gun too 3 1/2 inches and 2 mag pouchs will make it 5 1/4 , make sure your gun case can fit it .[ATTACH][ATTACH]
