Protos-M OWB Holster

The Protos-M OWB Holster from Black Arch Holsters delivers exceptional comfort, durability, and firearm protection for outside-the-waistband carry. Built around a 3/4 shell construction, this holster provides full trigger guard coverage and adjustable retention, ensuring your firearm stays secure and ready when you need it.

Designed specifically for OWB carry, the Protos-M offers a comfortable, close-to-body fit for superior stability and concealment under a jacket or loose clothing. Whether you're heading to the range or carrying throughout your daily routine, the Protos-M's lightweight, ergonomic design ensures all-day comfort while keeping your firearm easily accessible.

The Protos-M shell is also modular—allowing you to swap it seamlessly onto our Single Clip or Dual Clip Protos-M and Heritage backers for versatile IWB options, giving you flexibility without purchasing a completely new holster.

Key Features:

  • 3/4 Shell Design: Provides rigid protection for the trigger guard while reducing bulk for enhanced comfort.
  • Optimized for OWB Carry: Secure, close-to-body fit for stability and superior comfort.
  • Built-In Cant: Slight forward cant for an optimized draw angle, improving draw speed and natural firearm presentation.
  • Modular Flexibility: Shell can be placed on Black Arch’s Single Clip or Dual Clip Protos-M backers for IWB options.
  • Comfort-Focused Fit: Ergonomic, lightweight design for extended wear during daily carry or range use.
  • Exceptional Accessibility: OWB positioning allows for a natural, rapid draw every time.
  • Secure Retention: Precision-molded shell keeps your firearm securely in place with adjustable retention.
  • Durable Construction: Built with premium materials for long-lasting reliability and performance.
  • Concealment Ready: Low-profile OWB design works with jackets, untucked shirts, or loose clothing for discreet carry.
  • Versatile Carry Use: Perfect for range days, everyday carry, hiking, or open carry while working outdoors.
  • Sweat Guard: Protects your firearm while keeping it off your skin for added comfort during extended wear.

The Protos-M OWB Holster combines the durability and accessibility of outside-the-waistband carry with the sleek, low-profile design Black Arch Holsters is known for. Its modular 3/4 shell allows you to adapt to your preferred carry method while offering the stability and comfort needed for all-day wear. Whether you're at the range, on duty, or going about your daily routine, the Protos-M OWB keeps your firearm secure, accessible, and ready when it matters most.

Best hybrid holster I own

This holster has excellent retention and is crazy comfortable to wear just like my Black Arch IWB hybrid holster. Keep up the great work.

Two Black Arch holsters and still going strong — really glad both are earning their keep! Thanks for the photo and the kind words!

Great Hybrid Holster!

Love this holster! Very comfortable with a full sweat shield. You get the best of both worlds! The reliability and smooth draw of kydex with the comfort of a thick leather backing. Adjustable retention screws and about a 15 degree cant for a quick draw. Black Arch did a great job on this one!

That's a great breakdown of exactly what we were going for with the hybrid design! Thanks for the kind words and the photo — really appreciate it!

A tank of a holster

Been using this for the past 6 months or so as an almost daily holster so I am ready to post the review.....
It isn't a holster its more of a tank!
The leather backer is super thick and yet comfortable to wear. It certainly is NOT going to get so soft that it will not hold its position!
The retention is positive both audibly as well as tactile. You can have faith that it is in place and isn't going to fall out.
The fit is great and it really keeps the pistol close in and doesn't print much at all. I wear this under a light untucked shirt and I am good to go.
This is definitely a holster that will last you for a very long time.

Great quality holster

This holster wasn't just piece of kydex heated over a blank gum. Quality engineering. Yes, yes, I would highly recommend. In-additon, they answered all my question within a couple hours.

We appreciate the kind words and the sharp eye for quality. You're absolutely right—our holsters are engineered, not just molded. It's great to hear our support team took care of your questions quickly too. Thanks for the recommendation and for choosing Black Arch.

By far the most secure, high quality, and comfortable holster I have ever purchased. Blackarch will be my first and only stop for my holster needs moving forward.

Quility built but very uncomfortable for a larger guy

Now help fill a drawer

Thanks for the 3 stars and the kind words on the build quality! Sorry it isn’t comfortable for you. Shoot us a message and we’d love to help find something that works better for your build, so it doesn’t end up in the drawer.

Excellent OWB holster. Holds the gun exactly where I want at the perfect angle. Will be getting more from Black Arch.

Thanks for the 5 stars, glad the OWB is holding the gun right where you want it at the perfect angle! Looking forward to your next order.

Truly love the OWB Protos-M product. The holster is super comfortable. And I love the hybrid of leather and the Kydex. The Kydex fits the gun perfectly. I like the size, which is towards the smaller size compared to my other holsters. So for concealed carry, it's perfect.

Hi William, we're thrilled to hear you love the OWB Protos-M! It's great to know it's comfortable and perfect for concealed carry. Thanks for sharing your experience!

My [new] absolute favorite

I had already fallen in love with the IWB single clip Protos - but decided I wanted to give the OWB a try and the leather pancake holster always leave me feeling a little uncomfortable about retention. Picked up one of these and my word is it amazing. Retention is fantastic, the thick backing keeps the holster locked in place, and it is just plain comfortable. For days when I am wearing a sports coat, this is my new go-to. I can't recommend Blackarch's products highly enough, and they are a great company to deal with.

Hi Kevin, we're thrilled to hear you're loving the OWB Protos-M®! It's great to know it's become your go-to for those days with a sports coat. Thanks for your kind words and for choosing Black Arch Holsters!

Love this OWB holster

Very sturdy holster. Thick leather so the holster doesn’t move on your belt. Glad I chose the OWB PROTOS-M® FOR SIG SAUER P365-AXG LEGION GEN 2.

Thanks for the 5 stars, glad the OWB is staying put on your belt and feeling sturdy! Appreciate you picking the P365-AXG Legion Gen 2 version.

Exactly what the GTO was looking for

Bought 3 different holsters from 3 different companies. The black arch holster was the only holster that wasn’t returned.

Thanks so much for the 5 stars, and for putting us through the test against the competition! Glad the Black Arch holster was the one that stuck.

OWB Protos M A gem

After a couple of disheartening choices, I finally received this holster from Black Arch that's a keeper. It fits my Walther PDP Compact perfectly: smooth draws, a solid holstered fit and comfortable to wear. Well made. Thanks, I can throw away the rest.

Best OWB holster I've found.

I purchased the Protos-M OWB in FDE, and could not be more pleased. I searched for a LONG TIME trying to find a holster with a sweat guard and that would stay to my side with minimal printing. This one is the ticket! The retention is phenomenal and can be adjusted to preference. I have IWB holsters, and I just don't like wearing them all day. This holster is super comfy and good for all day.

Hi John, we're thrilled to hear you're so happy with the Protos-M® holster! Thanks for sharing your experience and for choosing Black Arch Holsters. Enjoy your comfortable, all-day carry!

Great Holster

This is a great holster for my p365 xmacro! It keeps the pistol very close to my body and has great retention with the kydex click when holstering the pistol.

I must have misunderatood. This was the only holster i saw that would fit the optic. This is only dor a hellcat. Not a pro. Doesnt look like black arch has one for pro as i did not see it in the drop down.

Sorry about the misunderstanding that led to this one star review. We absolutely have an optic cut holster for the Hellcat Pro. Shoot us an email and we will get an exchange set up right away. (No restock fee or anything)
