Multi-Angle Hip Holster
A holster is basically a housing for your pistol when it's not immediately needed, but you still want it close to hand. Given that description it is easy to see why hip holsters are the most popular - they mount onto a belt to a stable part of the body, and are well within reach as well as offering a comfortable draw. The question isn't 'why choose a hip holster?' but rather 'why use anything else?'
This particular model is manufactured by Swiss Arms out of durable nylon codura and is designed to fit the vast majority of common-size pistols e.g. 1911, M9, EU-Series, SIG, Walther PPQ, USP etc.
As the name of the product suggests, there is more to this holster than meets the eye. Unfortunately no, it doesn't turn into anything, but you can mount it horizontally or vertically depending on your setup. This is particularly useful for those wearing tac-vests - mounting the holster horizontally allows for a more condensed loadout whilst not impeding on the draw.
The holster is secured in place via velcro straps; one set for the traditional vertical mounting, and another set for the horizontal belt loops. This system prevents the holster from moving around, or randomly changing angle on you.
