Adjustable Retention Modular System (A.R.M.S.)

The Adjustable Retention Modular System or A.R.M.S. by CrossBreed Holsters is the perfect combination of modularity and adjustability. This versatile system is designed to accommodate your active lifestyle with ease by giving you multiple options for carrying. Whether you're at work, on a jog, in the woods, or even just enjoying an evening at home the A.R.M.S. has you covered.

Adjustable Retention is Perfect Retention

The A.R.M.S. Holster features a Reckoning style pocket designed to perfectly fit your firearm with multiple points of retention adjustment. By simply tightening the screws that mount the pocket to the leather backer you can ensure that you have the perfect amount of retention to meet your carry requirements.

Multi Options to Meet your Carry Needs

Your active lifestyle means you need the ability to carry your firearm in different ways to accommodate multiple situations, and the A.R.M.S. does just that and more. The holster itself has hook Velcro® installed on the back of it, giving you the ability to mount it to any number of loop Velcro® items. To complete your system, you have the option of picking one of many of our different platforms including a Belly Band, Purse Defender, or Pac Mat. These features combined means you can transition from your belly band at work, to hook and loop fastener in your vehicle console while driving home or maybe a purse while you're at the store to your hiking bag in the woods, no matter the situation the A.R.M.S. by CrossBreed has you covered!

Lifetime Warranty

Two Week, Try it Free Guarantee and Lifetime Warranty – As with all of our handcrafted holsters, CrossBreed stands behind the quality of each and every A.R.M.S. Holster with our legendary Lifetime Warranty and Try It Free, Two Week Guarantee. If your holster ever fails from normal use you can rest assured that CrossBreed Holsters has your back! *Lifetime warranty applies to the holster only and not the mounting option (IE: Purse Defender Backer, Pac Mat Assembly, Belly Band – Band)*

To find your exact Belly Band size, simply use a soft measuring tape around the area where you want the band to be worn (i.e. your waist, belly, or torso). If you measure at the end of a size, such as 36”, which would be a Medium we would recommend going up to the next size of Large.

All Modular Holsters and Packages come default with a 4" Soft Loop Panel with peel and stick adhesive on the back

    Great holster

    I've been using Crossbreed Holsters IWB holsters for 15-20 years. This is another outstanding holster. I have a couple of backpacks and one small sling bag that I had been using with one of those hook & loop, fold up, just good enough pistol holder things. I never fully trusted that. This is made specifically for my pistol model (or at least every Glock in the core size group). The hook & loop thing only holds as tight as you can wrap it. With the A. R. M. S. Holster, you can adjust the retention level.

    Love this A. R. M. S. Holster

    I carry “Off Body” and this holster is perfect for attaching to my bag as-well-as several other Velcro bases. This was excellently priced for the amount of useage that it provides.

    Does the holster come with the same retention as the modular holster out of the box and this one just allows you to increase/decrease the retention as I desire?

    • Store Owner

      The A.R.M.S Holster and the Modular Holster are the same thing except the A.R.M.S. allows you to adjust the retention with a screw driver and the Modular Holsters Retention is set here at the factory.

    What is the width of the A.R.M.S. holster at its widest point; and does the hook-portion of the velcro cover the entire rear surface of the holster or is it just a strip?

    • Store Owner

      On average (depends on which firearm its made for) they are about 4.5" wide and the entire back is covered in hook side velcro.
