The Universal inside the waistband series Holsters are expertly designed to fit a variety of same-sized pistols. The IWBL is tailored for large-frame pistols, the IWBM for medium frames and the IWBS for small frames. To use, simply slide the holster inside your pants until both belt clips securely grip your belt. You can position the holster around your waist according to your personal preference. Retention is maintained through the pressure of your belt against the holster shell, while the flexible backing molds to your body for added security. The non-slip surface ensures the holster stays firmly in place. Keep in mind that these Universal IWB series holsters are compatible with numerous pistols but do not feature a standard passive retention mechanism, so avoid inverting the holster when not in use.
