I've 34" waist and wear a 36" 1 1/2 belt for carry. With my Infidel and 1911, I'm comfortable.
With the MTAC and a Glock 26, I think I'm going to either have to loose weight
or buy a 38" belt and bigger trousers.I know the Glock is thicker than the 1911, but the leather backing of the MTAC, while making it more comfortable on the kidneys, makes it thicker still.
I'm also having trouble wearing the MTAC in any position except 4:00. I hope that the leather of the MTAC will become more pliable and allow hip carry. I think appendix carry is right out, because of the width between belt hooks.
Also, the Glock pushes into the leather (and consequently me) a bit, making the mouth of the holster closed down, so that re-holster is harder than with the Infidel. I've loosened the holster some and it seems better, I just don't want to loosen it too much.
Just my thoughts on first day with the MTAC.
