Frequently Asked Questions
Will this holster fit a SIG P320 without a weapon light attached?
No — the BLACKHAWK T-Series L3D is specifically designed to accommodate the SIG P320 with a Streamlight TLR-1 or TLR-2 mounted. The light rail cutout is integral to the holster's retention and fit geometry, so a light-free P320 will not seat correctly or retain securely. If you carry without a weapon light, BLACKHAWK offers other T-Series configurations sized for the standard P320 frame.
How does the Level 3 thumb-activated retention work?
The L3D uses BLACKHAWK's Master Grip Principle, meaning the retention release is activated by your thumb as it naturally wraps around the grip during your draw stroke — no separate finger manipulation required. A secondary retention strap across the back of the slide provides an additional layer of security, making it extremely difficult for an unauthorized person to remove the firearm while still allowing the trained carrier to draw quickly and instinctively under stress.
Is this holster suitable for use in wet or high-humidity environments?
Yes. The T-Series L3D features a hydrophobic interior lining that repels moisture, preventing water from being trapped against your firearm's finish. The reinforced polymer shell is also resistant to warping and degradation from rain, sweat, and humidity, making it a dependable choice for outdoor duty use, range training in adverse conditions, or humid climates.
