Walther PDP F Series 4" & 3.5" and Streamlight TLR-7 X / TLR-7 A / TLR-7 HL-X IWB Holster | Inside Waistband Concealed Carry
The Four Brothers Holsters IWB holster is precision-engineered for the Walther PDP F Series 4" and 3.5", PDP F Series Pro-E 3.5", PDP F Series Pro-E 4" and PDP F Series Pro-X PMM paired with the Streamlight TLR-7 X, TLR-7 A, or TLR-7 HL-X weapon light. Designed for everyday concealed carry, this Kydex Inside Waistband (IWB) holster delivers secure retention, outstanding concealment, and all-day comfort.
Retention is engineered around the mounted weapon light rather than the firearm itself. Because of this design, the holster will only function when the Streamlight weapon light is installed on the pistol.
