The Rio Grande OT is the ambidextrous flagship of Tagua's Elite Series — a premium IWB/OWB-convertible leather holster crafted from extra-thick, grain-selected cowhide that sets the standard for leather quality in the multi-fit holster category. If you want one Tagua holster that does the most — IWB, OWB, ambi, optics-ready, max fit coverage — the Rio Grande OT is it.
Elite Series leather runs heavier than standard Tagua cowhide, resulting in a stiffer, more supportive shell that holds shape and retention geometry over years of daily carry. True ambidextrous design eliminates the need for separate left- and right-hand models, making the Rio Grande a practical single-SKU choice for retailers, multi-shooter households, and anyone who trains both strong-hand and support-hand draws. The holster converts between IWB deep concealment and OWB belt carry from a single rig, delivering maximum flexibility from a single purchase. Full optics-ready clearance accommodates most popular slide-mounted red dots (Holosun, Trijicon RMR, Sig Romeo Zero footprints).
Fitment covers 14 codes spanning the full spectrum of popular carry platforms from the Sig P365 and Glock 43 through full-size Glock 17, Sig P320, and 1911 platforms — the widest practical coverage in a single Elite-tier holster.
Handcrafted by Tagua's leather artisans since 2005 — backed by our Lifetime Warranty against defects in materials and workmanship.
