Frequently Asked Questions (FAQ)

Will this holster fit the M&P 9 Shield X with the thumb safety?
Yes. The holster is molded to fit both Shield X models, with or without the Thumb Safety.

Is this holster red dot compatible?
Yes. The holster profile is cut to clear most red dot sights, including optics that overhang the side of the slide.

How do I know if I have the correct Streamlight TR-8 Sub version?
Check for “1913” printed on your light and confirm it uses the #3 key provided by Streamlight.

Can I use this holster with a threaded barrel or compensator?
Yes. The open muzzle design accommodates extended barrels and most compensators.

What is a Modwing, and do I need it?
The Modwing is a concealment claw that helps reduce printing by pressing the grip closer to your body. Two inserts are included for adjustable concealment pressure.

How do I adjust retention or ride height?
Retention screws allow adjustment of draw resistance. Ride height and cant are modified by changing the screw position in the mounting slots.
