Looking at going from pocket carry with a mouse gun to something a little more substantial. While looking at different IWB systems there are the various hooks systems. The J-hooks look like they actually slip over the side of your pants and the "J" fastens at the bottom of the belt. This does not appear to actually use the belt to support the weight of the holster. Is this correct? The C-Hooks look as though they have the belt slip through them and actually hold the weight. This appears to be more difficult to take off and put on. Is this also correct? What about the tuckables? Appears to be the same system with the hooks but with room to tuck the shirt. Appears to be pretty difficult to actually tuck the shirt so as to be neat and non printing. About the hooks which all appear to be made of kydex. Is kydex only in black and is there any way to color the kydex to blend with different color belts? Brown!
