CERTUM4 vs CERTUM3: What Actually Changed?
This video details the specific changes between the Tenicor CERTUM 3 and CERTUM 4 inside-the-waistband holsters. Key upgrades include the elimination of the top blocking, an improved camming bar system mirroring the Velo 5, a simplified double post hardware system replacing square nuts, and the adoption of mirror-image Mod 4s for easier clip adjustment on both right and left-handed versions. The CERTUM 4 also offers enhanced stability with a third mounting position on the sight channel, allowing for wider clip spacing.
