Frequently Asked Questions

What are the main improvements in the new Tenicor CERTUM LUX4 holster compared to the older Kydex Lux?

The CERTUM LUX4 offers a universal fit for various light sizes, a simpler and more adjustable Mod 4 mounting system, increased rotation for better cant adjustment, and a lower-profile blocking for improved concealment. It consolidates features previously spread across different models.

How does the mounting system differ between the old and new Tenicor Kydex Lux holsters?

The old Kydex Lux used T1 clips with slot adjustment, which could be complex. The new CERTUM LUX4 features a Mod 4 clip and a double post system, providing a more streamlined setup with easier, mirror-image cant adjustment suitable for both right and left-handed users.

Does the new Tenicor CERTUM LUX4 holster offer better concealment than the older model?

Yes, the CERTUM LUX4 significantly improves concealment due to its much lower profile blocking. This design is more contoured to the firearm and belt, allowing the belt to flow over it more elegantly, unlike the older, more square and raised blocking.

When should a user consider upgrading from their old Tenicor Kydex Lux to the new CERTUM LUX4?

An upgrade is recommended if you desire a more refined design, better concealment, or more versatile light compatibility. If your current holster meets all your needs without issues, there's no urgent need to upgrade, but the CERTUM LUX4 offers notable advancements.
