This Inside Waistband (IWB) holster is purpose-built for concealed carry of the Glock 48 and Glock 48 MOS, with a comfort-forward length that also works brilliantly for the Glock 43 and 43X by extending past the muzzle to reduce grip tip-out and printing. It’s a confident, everyday solution for responsible owners who want secure retention, discreet concealment, and streamlined draw.
Each holster is engineered from a precision CAD mold, vacuum-formed, hand-finished, and test-fit on the actual pistol. Retention is user-adjustable so you can dial in the exact draw feel you prefer. A mid-height sweat guard balances comfort and access, and every edge is smoothed for all-day wear.
