Inside waistband holster designed to fit the Sig Sauer P365-380 pistol. We keep the material edges smooth and the overall size of the holster as small as possible to allow you to carry your P365-380 pistol all day, every day.

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 retention of the holster is easily adjusted so that the fit can be dialed into your personal preference.

FEATURES:

  • Full Sweat Guard
  • Adjustable Retention
  • Minimal material and smooth edges to reduce printing
  • Adjustable ride height and cant
  • Made from .080" thick thermoplastic for durability
  • Optional Modwing includes 2 inserts to allow the user to adjust the amount of leverage placed against the inside of the belt to reduce firearm printing
  • Proudly made in the USA

    Excellent quality IWB holster From 4Bros

    I ordered an IWB holster for my Sig P365-380 from 4Bros. It arrived right on time and was properly packaged. The materials and the build quality are both excellent! And it fits the pistol quite nicely, much unlike the holster I ordered from KSG Armory which I had to return because it had 5/16" of free-play movement between the top of the slide and the holster. KSG Armory insisted the free-play movement between the top of the slide and the holster was less than 1/16". So, apparently, who ever took the measurements At KSG is blind, or maybe they use a different method of measuring? At least they gave me my money back.
    I have extra large hands with extra long fingers, so finding a holster which has the proper ride height to allow me to draw my gun with a full combat grip is difficult.
    But, my 4Bros holster offers enough ride height for me, and using the claw attachment allows the holster to keep the grip of the gun right up against my slightly muffin top body. If this holster were to become damaged, I would immediately replace it with another just like it from 4Bros. Thanks Guys!

    Outstanding craftsmanship and quality

    Purchased for a P365 .380 with Romeo Zero. Couldn’t be happier. Exceeded me expectations. Great retention and extremely comfortable. Highly recommend.
