Are you thinking about a regular style belt or a 2 piece competition belt? I use a 1 1/2" Uncle Mike's Reinforced Instructors belt and it defiantly has the iron clad feel about it. The only down side it once the holster is on I have to take it off to adjust it. Of course the simple fix is to put on the mag pouches first, adjust the belt and then put the holster on. Make sure to order one size large.
These are very common too and have the luxury of permanently holding your rig, no taking on and off piece by piece. Lots of guys wear them but I never got one myself.
