Uncle Mikes 74211 Reflex Open Top Holster 21 RH

The Uncle Mike's Reflex Open Top Holster 21 is a no-nonsense right-hand carry option built for shooters who want reliable retention without complexity. This paddle-and-belt-loop design uses Uncle Mike's Integrated Retention Technology (I.R.T.) to keep your Glock secure during movement while allowing a smooth, instinctive draw. The open top means faster access compared to fully enclosed designs, making it a solid choice for range days, training, or duty-style carry where speed and dependability matter.

Construction is injection-molded, impact-modified polymer—tough enough to handle daily use and weather without the weight or cost of leather or premium synthetics. The belt loop fits standard belts up to 1.75 inches wide, so it'll work with most tactical or casual carry setups. A removable paddle attachment is included, giving you flexibility to switch between strong-side belt carry and paddle mounting depending on your rig or wardrobe. Made in the USA, this is the kind of gear that does its job quietly and lasts.

Uncle Mike's has built a reputation on making straightforward, affordable holsters that actually work in the field. The Reflex 21 isn't fancy, but it's honest—designed for Glock full-size and compact models in 9mm Luger, .40 S&W, and .357 SIG. If you're outfitting a truck gun, a backup piece, or just want a no-frills option that won't break the budget, this holster delivers on function.
