Blackhawk Omnivore Review: Honest Experience & Pro Hacks

If there’s one thing I’ve learned over the years as a firearms enthusiast, it’s that finding the perfect holster is almost as challenging as choosing the right firearm. That’s why I was excited to try out the Blackhawk Omnivore MultiFit Holster—a universal option that promises compatibility with over 150 different handguns. It sounded too good to be true, and I had to see if it lived up to the hype.

After spending weeks with the Blackhawk Omnivore, here’s my full, hands-on review, including its features, problems I encountered, and the hacks I discovered to make it work even better.

First Impressions

Right out of the box, the Blackhawk Omnivore looked sturdy and well-built. It’s primarily made of reinforced polymer, which gives it a rugged feel without being overly heavy. Unlike traditional holsters that mold specifically to one firearm, the Omnivore is designed to work with any pistol equipped with a rail-mounted light or a passive retention device.

I tested it with my Glock 17, SIG P320, and Smith & Wesson M&P 9—and all fit securely once I attached the included Rail Attachment Device (RAD). The installation process was fairly simple: just attach the RAD to your rail and snap the gun into place.

But here’s where I hit my first roadblock…

Bulkiness & Ride Height

The Omnivore is a big holster—bigger than most I’ve used. If you’re used to a snug, low-profile fit, this holster might feel bulky at first. Wearing it for extended periods, especially inside the waistband (IWB), was not ideal.

Solution: Use a Different Belt Position & Adjustable Cant

I found that adjusting my belt position and canting the holster slightly forward made a significant difference. Also, if you’re using it for open carry, the extra size won’t be an issue. For concealed carry, though, you’ll need a thicker belt or a different placement (appendix carry is a no-go with this one).

Secure but Stiff at First

One of the standout features of the Omnivore is its active retention system. Instead of relying on friction or a standard thumb break, the holster features a thumb release button positioned near where your trigger finger naturally rests.

At first, I found the retention very stiff. Drawing my firearm wasn’t as smooth as I’d like—it felt like I was fighting the holster rather than smoothly unholstering my gun.

Hack: Break it in with Dry Fire Drills

I practiced about 50-100 dry-fire draws over a few days, and it made a massive difference. The release button loosened up just enough to allow a natural draw while still keeping my firearm secure.

Pro Tip: If you want an even quicker break-in period, apply a small amount of dry silicone lubricant to the release button.

What Most People Might Not Notice

During my time with the Omnivore, I discovered a few details that aren’t immediately obvious but can make a huge difference in user experience.

1. Not Compatible with Every Rail System: While the Omnivore supports a wide range of firearms, some handguns with proprietary rails (e.g., certain Walther and HK models) might not fit perfectly.
2. Works Best with Tactical Lights: If you use a SureFire X300, Streamlight TLR-1, or similar rail-mounted light, the fit is significantly better.
3. Holster Angle Can Be Adjusted: You can fine-tune the draw angle by repositioning the belt loops, which many users overlook.
4. No Manual Retention Adjustment: Unlike some holsters where you can tweak retention tightness, the Omnivore only relies on its built-in active retention system.

Who Should Buy the Blackhawk Omnivore?

Buy This If:

• You own multiple handguns and want a single holster to accommodate them.
• You prefer open carry or need a duty holster for tactical applications.
• You use a rail-mounted light and want a secure retention system.

Skip This If:

• You’re looking for an inside-the-waistband (IWB) holster.
• You need a super lightweight, low-profile conceal carry option.
• Your firearm doesn’t have a rail or tactical light attachment.

Final Thoughts

After weeks of testing, I can confidently say the Blackhawk Omnivore is a solid choice if you want a universal holster that offers secure retention and wide compatibility. However, it does come with a learning curve—the bulkiness and stiff initial retention can be frustrating until you get used to them.

If you primarily open carry, use a weapon light, or own multiple handguns, this holster is a fantastic investment. But if you’re strictly looking for a concealed carry option, this might not be the best fit.

Would I recommend it? Yes—but only if it fits your specific needs.
