Just do a forum search on the Supertuck. I can tell you with mine, Ive had for about a week, that it has got to be the closest thing to perfection! It does an amazing job of spreading out the weight, and the bulk of the gun(commander 1911 for me). you don't feel a bulge in your side, and it spreads the wieght over the 6 or 7 inches between the clips on your belt. Even with a crappy belt, mine is an extremely solid rig.... I could go on and on, but you will be very happy with them!!
Besides, have you seen the warranty?! I was going to order a Milt Sparks VM 2, but got the Supertuck and figured, I'll send it back if I don't like it and order the Milt Sparks.... but I don't know how it could get any better than this!!
