So through some misunderstanding about what was backordered and what wasn't I somehow ended up with both a Hank's Amish belt AND an Aker B21. Not complaining because I'll use them both. Wife was a little cranky about buying two belts.
I returned the 5.11 I originally ordered because it was much too small.
Both belts are well made, with good quality hardware. The Aker is much stiffer. It won't drape over a hanger or doorknob like a regular belt. It holds my carry gun up a little better (CZ75 Compact) than the Amish Belt. The Amish belt is very thick but more flexible. It's a little more comfortable to wear. Even though it's not as stiff it's more comfortable to cinch it up a little tighter, so it holds up the gun almost as well. The Aker is more dressy looking, while the Amish belt looks like an everyday work belt. The Amish belt is also slightly wider, maybe 1/8 inch.
I think they're both very good belts. I like the Aker more, but it costs quite a bit more. You do get what you pay for with the Aker, but either one is a very good concealed carry belt.
