Description
The GBRS Group x Priority 1 collaboration brings together two respected names in tactical gear to create a purpose-built IWB option for concealed carry with the Sig P365 XMacro. This holster is engineered with the modern carry setup in mind, whether you're running optics, threaded barrels, or going with a standard factory configuration.
Durable Construction Designed for Daily Use
Constructed from rugged 0.080-inch Boltaron thermoplastic, this holster delivers a low-profile platform that resists daily wear and tear. Boltaron is known for its durability and lightweight characteristics, making it suitable for all-day comfort without sacrificing strength. The material holds its shape through consistent draw cycles and environmental exposure, which matters when you're carrying the same gun every day.
Adjustability That Actually Works
The signature feature here is the adjustable screw-on retention system. You control how tight the holster grips your P365 XMacro by tuning two screws to your preference. This matters because retention preferences vary from person to person based on how quickly you want to draw and how much security you need while moving. Additionally, you get adjustable cant at 0 or 15 degrees, plus adjustable ride height for positioning that fits your body and your clothing.
Ready for Modern Pistols and Accessories
The open-ended muzzle design cuts a straight line across the front, allowing the gun to sit lower in the holster while accepting threaded barrels or compensators. The optics-cut profile includes a molded channel that clears most slide-mounted red dots and supports tall suppressor-height sights. A Discreet Carry Monoblock clip secures the holster inside the waistband with or without a belt, giving you carry flexibility.
A concealment wing is built into the design to rotate your grip toward your body, which reduces printing and adds stability when you're moving or bending. Real-world carry feedback shows smooth draw and reholster cycles, with the belt clip securing the holster firmly during activity.

Frequently Asked Questions
Will this P1 IWB holster work with my Sig P365 or P365XL?
No, this holster is molded specifically for the P365 XMacro. The XMacro grip is 5.2 inches tall, which is different from the standard P365 and P365XL. Using a holster designed for a different variant will result in poor fit and inconsistent retention. You need a holster that explicitly lists the P365 XMacro.
How do I adjust the retention on this GBRS holster?
Two screws control retention. Tightening them increases draw resistance, while loosening them makes the draw smoother. Start with the factory setting and adjust from there based on how quickly you want to draw and how much security you prefer while moving or bending. Most users need minimal adjustment.
Can I use this holster without a belt?
Yes. The Discreet Carry Monoblock clip is designed to work with or without a belt, though a quality belt provides better support and stability during movement. If you prefer beltless carry, make sure the clip has a firm grip on your waistband.
Does this holster fit the P365 XMacro with a light attached?
This version is for the XMacro without a light. GBRS Group makes a separate P1 holster specifically molded for the XMacro with a Streamlight TLR-7 Sub. If you have a light mounted, you'll need to order that version instead.
