FOUR BROTHERS HOLSTERS
Couldn't load pickup availability
Outside Waistband Holster designed to fit the Sig Sauer P320 Carry, Compact, and M18 pistols.
The holster functions well with the Wilson Combat Carry Module.
Product Details:
Our holsters are vacuum-formed with a precision machined mold designed from a CAD model of the actual firearm.
Each holster is formed, trimmed, and folded in-house. Final fit and function tests are done with the actual pistol to ensure the holster fits the gun and has the correct amount of retention.
The holster's retention is easily adjusted so that the fit can be set to your personal preference.
This holster does not have clearance for threaded barrels. (Closed muzzle)

*We strongly suggest you apply a removable thread locker to each screw of your holster after you receive it to prevent lost screws while the holster is in use.
• Full Sweat Guard

• Proudly Made in the USA
Made in America. Founded, located, engineered, manufactured, and shipped from Northern Indiana.
