Gramas is a company that makes cases and holsters for firearms, such as pistols and rifles. This company has been around since the late 1800's and has been making cases for firearms ever since. Gramas cases are made of genuine cowhide leather with a heavy-duty nickel-plated steel buckle. The cases have a self-retractor spring mechanism that allows the case to be opened by hand or with a single pull of a lever. This is a great feature for cases that have belt loops, as it allows the case to be opened quickly and easily without having to take the belt off. Gramas offers five different models of holsters that fit for both pistols and rifles. The first model they offer is the "Tactical Holster." This holster is designed with the military in mind and features a single strap with an adjustable quick draw option. The second model they offer is the "Lightweight Tactical Holster." This holster is also designed for a quick draw option, but it is made from full-grain cowhide leather rather than nylon. The third model they offer is called the "XRSH Holster." This holster has a fully-adjustable belt loop, but it only has one set of adjustment points. The fourth model they offer is called the "Classic." This holster features a single strap with an adjustable quick draw option. The fifth model they offer is called the "XSH Holster." This holster has a fully-adjustable belt loop, but it only has one set of adjustment points.
