If you are going to carry SERIOUSLY, you need to get a serious gun belt. It needs to be reinforced to hold up and support a firearm. It will last you many years.
Sure, you can get a $30 dress belt from Sears and it'll last 6 months of daily carry - heck, you can probably put up with it for a year or so. But, it's going to sag at the top and this will make your carry gun print more as it bows out from the body. Or, you can get a good gun belt and it will last you years - 10 or more if you take care of it. So, $30 every six to twelve months times 10 years, $300 min - or $60 for 10 years. Pay for quality once.
Of course, some people just love packing their serious CCW in a nylon $25 gun show tactical special, with the requisite spring steel clip. Or you can pack in a nice Milt Sparks or Galco leather holster.
I am 5'08" and pack a P220 and 2 spare mags under a T-shirt. Let's see you do that with a nylon tactical black gun show special holster.
