Slim Fit Holsters is excited to announce that we now offer holster support for the SureFire XC3 Sub. This gives customers another option for building a compact, light-bearing concealed carry setup.
What makes the SureFire XC3 Sub particularly interesting is its mounting system. Unlike many subcompact weapon lights that are designed around one specific rail interface, the XC3 Sub is designed to work with both 1913-style accessory rails. Additionally, it works with the Glock Slimline MOS accessory rail found on pistols such as the Glock 43X MOS and Glock 48 MOS.
That versatility allows the XC3 Sub to be used across a broader range of compact and subcompact pistols. At the same time, it maintains the small footprint expected from a concealed-carry weapon light.
Holsters for the SureFire XC3 Sub
At Slim Fit Holsters, we now have the SureFire XC3 Sub available as a weapon-light option for supported firearm configurations.
Because light-bearing holsters typically index and retain around the weapon light, proper XC3 Sub fitment is important. Our compatible holsters are built around the firearm and XC3 Sub combination selected when ordering. Rather than treating the light as a universal add-on, we focus on precision.
This allows customers to take advantage of the XC3 Sub’s compact design. At the same time, they still get a holster made specifically for their carry setup.
One Compact Light, Multiple Rail Systems
One of the standout features of the SureFire XC3 Sub is its ability to accommodate different compact-pistol rail systems.
The light can be configured for:
- MIL-STD-1913 / Picatinny-style rails
- Glock Slimline MOS rails, including the accessory rail used on the Glock 43X MOS and Glock 48 MOS
For shooters who own multiple compact pistols or prefer a light that isn’t restricted to a single proprietary mounting system, this makes the XC3 Sub an especially versatile option.
SureFire XC3 Sub Holsters from Slim Fit Holsters
Whether you’re setting up a Glock 43X MOS or another supported pistol equipped with a 1913-style rail, Slim Fit Holsters can now accommodate configurations using the SureFire XC3 Sub.
As always, available firearm, light, optic, and carry configurations depend on the specific holster model selected.
