Bianchi® holsters are built to exacting standards for the correct fit and retention. Knowing your firearm type, make, and model are critical to getting the right holster fit. Much like the car industry, manufacturers create various gun models over time. Different models could have differences in size, shape, caliber, or be single- or double-column mag. It’s important to know that some manufacturers change the specs of their models every few years, and that can alter the exterior holster fits.


The pistol is a handgun and a more popular choice for everyday carry than a revolver. In comparison they are quicker to reload, have a lighter trigger and are generally slimmer and weigh less. In today’s law enforcement world, almost all officers are going to carry a semi-automatic pistol.

They are slow to reload, but the common consensus is that they don’t malfunction, and guarantee that all rounds can be fired. In the public safety industry, the revolver is more likely to be used by security officers or in foreign markets. As an exception there are plainclothes or detectives that may carry a revolver as a primary weapon, or as a backup.
