Good service..trustworthy and excellent delivery. Was everything we had paid for. What was advertised was even in excellent condition. Will recommend Gunman SA to everybody. Thank you for the 5star service.

Oliana De Villiers

Very good product for a universal belly belt my 38 special snub nose revolver fits in perfectly. You can carry it 3 or 4 O clock position apendix or under the arm a lot of storage if you carry a pistol there is pouches for two extra mags. I use one pouch for my leatherman and the other for a folding knife. The ziplock pouch is great for carrying keys, cellphone or bank cards holder. The product making everything concealable. Just make sure you wear one size bigger shirt or that is nice and loose not tight against the body to prevent printing.
