What holsters are compatible with the PHLster Enigma OS?

The Enigma OS accepts a variety of compatible holsters from other manufacturers. The specific holsters depend on your model: the Standard Enigma OS has its own compatible holsters list, and the Light Bearing Enigma OS has a separate list for holsters that accommodate weapon-mounted lights or lasers.

What is the difference between the Standard Enigma OS and the Light Bearing Enigma OS?

The Standard Enigma OS is designed for firearms without a weapon-mounted light or laser. The Light Bearing Enigma OS is designed for firearms with a weapon-mounted light or laser attached. The two models use different mounting hardware and are not interchangeable.

Does a red dot sight on my gun affect which Enigma model I need?

No. A red dot optic mounted on the top of your slide does not affect which Enigma model you need. Only weapon-mounted lights and lasers that attach to the rail on the front of the frame determine whether you need the Light Bearing model.

Do I need to have my holster before ordering the Enigma?

Yes. You should have your compatible holster in hand before ordering your Enigma, as you will need it during the assembly process.

Where can I find assembly instructions for the PHLster Enigma?

PHLster provides both written guides and video walkthroughs on their instructions page. If you need additional help during assembly, you can contact PHLster Support.

Step 1

Find a Compatible Holster

Before ordering an Enigma, you need a compatible holster in hand. The right holster depends on whether your firearm has a weapon-mounted light or laser. Choose the option that matches your setup:

My gun does NOT have a light or laser

Great — you need the Enigma OS - Standard. Browse the compatible holsters list for the Enigma OS - Standard to find a holster that fits your firearm.

Once you have your holster in hand, order the correct Enigma model:

My gun HAS a weapon-mounted light or laser

You need the Enigma OS - Light Bearing. Browse the compatible holsters list for the Enigma OS - Light Bearing to find a holster that accommodates your firearm with its light or laser attached.

Once you have your holster in hand, order the correct Enigma model:

Shop Enigma OS - Light Bearing

I’m not sure — what counts as a light or laser?

A weapon-mounted light (WML) is a flashlight or laser that attaches to the rail on the front of your firearm’s frame, beneath the barrel. If your gun has one of these, you need a light-bearing holster and the Enigma OS - Light Bearing.

A red dot optic mounted on top of your slide is not a light or laser — it does not affect which Enigma model you need. Learn more about identifying your sight: What sight is on my gun?

If you have a laser only (no white light) and are unsure which model fits, check both compatible holster lists above. Many laser-equipped holsters work with the Enigma OS - Standard, but some require the Light Bearing model.
