T.Rex Arms has released the Titan, a Level 2 retention outside-the-waistband holster designed for duty use that uses Kydex with an integrated mechanical lock engaging the pistol ejection port.
The holster comes in versions for various handguns, with options for a removable optics hood, Safariland QLS mounting compatibility, adjustable belt positioning, multiple colors and patterns, and custom pistol-and-light combinations, plus a lifetime warranty and 60-day returns at roughly 135 dollars.
A user who carried a Titan daily for two months on a Shadow Systems DR920 with SureFire X300, and also fitted a Ruger RXM, described it as well made with secure retention, though the optics hood detent released too easily from arm contact.
