Perun OWB Holster Glock 19

Current stock: 0

The Perun is our flagship outside-the-waistband (OWB) holster.  It is the result of blending the best features of two of our most popular holsters, the Eidolon and the Phantom, to create a highly refined, exceptionally concealable holster.    

The Perun is designed to be the best modular OWB “pancake” style holster on the market.  It has a body-hugging design that rides high for maximum concealment.  The body of the holster is only slightly larger than the pistol contained in it.  This small size aids in concealment while also making the holster more comfortable while seated in a vehicle.

The body-hugging curvature of this holster is accomplished using modular belt loops.  Each holster includes three pair of 1.5” belt loops (LH 10 degree cant, RH 10 degree cant, and ambi 0 degree cant), which allow the end-user to configure the ambidextrous holster body for left-handed or right-handed use, with either a 0-degree or 10-degree cant.

Retention in the Perun is crisp, defined, and consistent, thanks to innovative design features inside the holster body.  The unique retention slider makes adjusting retention as simple as turning up the volume on your stereo.  And unlike other holsters that use the traditional “screw through a rubber grommet” style of retention, the Perun’s retention will not back off after repeated drawing and re-holstering.

The Perun is compatible with most slide-mounted red-dot optics (like the Aimpoint T-1, Trijicon RMR, etc.) and accommodates suppressor-height front sights up to .350” tall.  It is also fully compatible with the RCS Balor optic mount. The Glock Perun is compatible with generation 3-5 Glock pistols. The Perun is compatible with all small frame 9mm, .40S&W, and .357sig Glocks. Example, The Glock 17 Perun will fit the corresponding standard full sized pistols such as the .40 G22 and .357 G31. The Glock 19 Perun will fit the corresponding compact sized pistols such as the .40 G23 and .357 G32

The muzzle-end of the holster is rounded for comfort, yet has an opening sufficient to accommodate most common after-market extended and threaded barrels (with thread protectors).  The opening at the muzzle is also specifically designed to allow foreign objects (like spent casings) to drop out the bottom so that nothing can block your pistol from being safely re-holstered.

The ambidextrous holster body has both inboard and outboard full-height body shields.  These body shields offer some protection for your pistol from sweat, as well as protecting your skin and cover garments (especially the thin material used for linings in sport coats and suit jackets) from being abraded by the serrations on the rear of the slide.  They also enhance safety by helping keep cover garments and other foreign objects from falling into the mouth of the holster while you have your pistol drawn, and aid in proper, safe muzzle orientation during re-holstering.

The holster is injection molded from a proprietary, extremely high-strength polymer blend that is significantly more durable than Kydex or Boltaron.  Like all RCS products, it is made in the USA, and is backed by our lifetime warranty.

*Legacy belt attachments are NOT compatible with the Perun holster.


PLEASE NOTE: .40 S&W and .357 Sig are calibers of ammunition.  This Perun will accommodate GLOCK pistols chambered in either of those two calibers.  Do not order this holster thinking it will accommodate a Sig or S&W pistol, simply because those words are part of the name of a caliber. It is a GLOCK holster and will not accommodate a S&W or Sig pistol.

Replaced my legacy Raven OWB Holster I have been using at work for the past 7 years. I work in plain clothes (always concealed) and do not need a level 2 or 3 holster but the adjustable retention system on the PreRun is fantastic. I had the perfect amount of retention dialed in for my new Glock M45 within minutes. I like how low profile the holster is and the 10% adjustable cant is perfect for carrying a Glock 17 or 19 under a sport coat. Just buy one!

As always a great RCS Gear Perun Holster

I just built a Churched up custom G19 and knew I had to have this Perun and also a Vanguard from Raven Concealment. The best products on the market.

Perrin holster

Quickly became my favorite holster. Like the way it holds the weapon snug to my hip. Very comfortable.

Awesome holster, OUTSTANDING customer service

I am not a fan of IWB holster and was waiting for a company to make the perfect OWB holster. As always, RCS came through and created the PERUN. I also order a pair 2 pairs of pancake wings; one for my Glock 17 PERUN and Glock 19 PERUN. I did not know that the pancake wings were incompatible with the PERUN as their belt loops were already fitted to hug the body close. Ms. Kathy, immediately contacted me and informed me of the discrepancy and refunded the order for the pancake wings. Not only did I get a pair of awesome holsters but Ms. Kathy took the initiative to assist me. Thank you RCS, ya'll are the best holster company in the world!

Perun OWB holster

I was considering an Eidolon, but AIWB holsters are not too comfortable for me. So , I ordered the Perun. It fits the gun nicely. No problem wearing it with my Ares belt. And the price is reasonable.

This is a fantastic holster for the money.

In my opinion this is the best mold injected holster on the market.

Doesn’t work for polymer 80

Only took about 3 or 4 daysfrom being ordered to being in my hands, that’s impressive. I haven’t really had a chance test it though since it doesn’t fit my polymer 80 frame due to the larger trigger guard.

I love this holster it is by far the best holster I have ever tried. It is so comfortable and sits at a very combltable height for owb concelment. I now use this holster over my others even on a non concelment applications like when I run around in the woods with amazing retention. This thing is awsome!
