thebeltman.net You can buy a cheaper belt, but trust me, they won't hold up in the longer run nearly as well as the Beltman's and you'll find yourself replacing your cheaper belt long before you can wear out a Beltman belt.
My first gun belt lasted one year before it broke down. My Beltman is 3 years old and is just as stiff as when it was new. It's been a great investment especially when you consider I paid $60 for my first belt that lasted a year and $100 for my Beltman that is still going strong.
I read many years ago that for best performance, it's a good idea to get the holster and belt from the same maker.
The belt should be high quality and be able to hold the weight of a loaded handgun & related gear(magazines, speedloaders, white-light, folding knife, cuffs, etc). Writer & EP expert Leroy Thompson says 1.5" width belts do best for most med/large DA revolvers or duty size pistols.
I finally graduated to a Beltman product but before my budget would allow it, I purchased a "Garrison" belt from my local Army surplus store. These belts are generally twice as thick as regular dress belts. They are a far cry from a Beltman product, but when your money is limited, these belts will make a fair substitute. Check you Army surplus store.
