Kramers Horsehide (double thickness) gun belt is superb and holds its stiffness for a loonnnnnng time. I would only get it in black, as horsehide does not like lighter colored leather dyes (blotchy finish). They are expensive, around $125 or so, but so far I have not fond a better gun belt in my 35 years of toting a shootin' iron.
The cowhide belts I've had over the years start out stiff and rapidly get too soft to properly support a OWB holster. I do not like a really wide gun belt because it screams GUN BELT. I like an 1 1/4" belt that looks like just a plain belt.
I used to laugh when I would see an off duty LEO that was wearing a 1 1/2 - 1 3/4" Bianchi belt with typical "gun belt style" stitching with a suit jacket. Anybody who knew anything knew what was on the belt.
There are cheaper belts on the market, but IMHO none better than the Kramer.
