Choose the exact firearm model and weapon-light combination listed for the holster. Light-bearing holsters are generally molded around both the firearm and the specific weapon light, so the light model matters just as much as the handgun model. If you are unsure, contact us before ordering with your firearm model, generation, weapon light, optic, and preferred mounting setup.

It can. Some configurations work across multiple generations while others may require a specific fit. If your generation is not clearly listed on the product page, contact us before ordering.

Many Solid Mass Defense holsters are designed with open optic clearance and work with common slide-mounted red-dot sights. Check the individual product listing for confirmation.

No. If a holster is listed for a SureFire X300, Streamlight TLR-1, Olight PL-3, or another specific light family, use the listed light. Light-bearing Kydex holsters typically index and retain around the weapon light, so substituting another light can prevent proper fit and retention.

A light-bearing holster should be used with the intended weapon light installed unless the product page specifically states otherwise. Removing the light can significantly change retention.

Level 1 retention uses passive friction or adjustable mechanical tension to retain the firearm. There is no additional active release device that must be defeated during the draw.

Level 2 holsters add an active retention mechanism in addition to the holster's passive retention. The user must deliberately operate the release during the draw.

Where the product design permits it, retention can be adjusted using the holster's retention hardware. Make small adjustments and confirm that the firearm remains secure while still drawing smoothly.

QD means quick detach. QLS commonly refers to Safariland's Quick Locking System, which uses a fork-and-receiver setup that allows compatible holsters to be quickly attached to or removed from a belt, drop-leg platform, or other mounting location.

Included mounting components can vary by configuration. Check the individual product listing carefully to see exactly what is included.

Possibly. Send us the exact firearm model, generation, weapon light, optic, and the type of holster you want. We can tell you whether we currently support that configuration.

Yes. When tracking is available for your shipment, it will be sent using the contact information associated with your order.

Stop using it and contact us. Do not aggressively force the firearm into a holster that does not appear to fit correctly. We will first verify your firearm, generation, weapon light, optic, and ordered configuration to determine what is causing the problem.
