FOUR BROTHERS HOLSTERS
Couldn't load pickup availability
Designed for the Walther PDP 3.5" and 4" pistol models equipped with the Streamlight TLR-7 A or TLR-7 X, this Outside Waistband (OWB) Holster provides a secure, light-specific fit with the durability and versatility needed for everyday carry, range sessions, and training.
Constructed from rugged .093" thermoplastic, each holster features adjustable light-based retention, an optics-ready profile, and carefully finished edges for consistent performance.
This holster is designed to accommodate the following Walther PDP models:
Compatible Weapon Lights:
Light-Based Retention: This holster retains the firearm through the mounted weapon light rather than the pistol frame. The light must remain installed for proper fit and retention.
This holster is designed specifically for the listed firearm and light combinations. Other weapon-mounted lights are not compatible.
Important Fitment Requirement: The compatible Streamlight weapon light must be installed using the 1913-1 rail key for proper holster fit. This positioning helps minimize the gap around the trigger guard. The Walther PDP F Series 3.5" requires the Streamlight 1913 #4 rail key.
Preferred Light Option: We recommend the Streamlight TLR-7 X USB, available directly from 4BROS.
For additional specifications, view the Streamlight TLR-7 X Data Sheet.
A dependable holster starts with the right fit. Each 4BROS holster is shaped using a precision-machined mold developed from a CAD model of the actual firearm, allowing for consistent dimensions, proper clearance, and secure retention around the designated firearm and light combination.
From vacuum-forming to final assembly, every holster is formed, trimmed, and hand-finished in-house. Each unit is then individually tested with the actual pistol and mounted light to verify fit, retention, and smooth draw performance.
Adjustable retention hardware allows you to fine-tune the amount of resistance during the draw, so you can configure the holster to your preference.
Customize your outside waistband setup with available attachment options:

Holster fits firearm well. Retention keeps it from falling out. Made well, shipped fast.
The only complaint I have with that holster so far is there’s a special backings screw that goes in the Safari land mount when the holster arrived it only had one. The other two were just standard holster screws and backers. Other than that the holster seems well-made. I will update my review after some range time.
Fits nicely
It's ok. When you take off the light it doesn't fit secure. It made cheaper than my other one the is appendix
I love this holster! More importantly, I realized two days after ordering that I forgot to include the light option. I reached out to customer service, and they got back to me right away to help fix the order.
Thank you for the great service!
Product is great, fit is perfect!
