The Hawke Endurance Reflex Dot Sight 1x21 (Model 12150) is an ultra-compact, non-magnified red dot optic engineered for fast target acquisition across pistols, rifles, and shotguns. Built with a 21 mm objective lens, it features a user-selectable multi-reticle system consisting of a 3 MOA Dot, a 30 MOA Circle, or a combined Circle-Dot reticle. Operating on a direct Shield RMSc footprint with an included low-profile Weaver and Picatinny adapter base, this sight integrates directly onto slimline pistol slides or standard rail platforms. Its anodised aluminium chassis weighs 26 g on its own and is fully waterproof, shockproof, and rated for all calibres.

Who is the Hawke Endurance 1x21 Reflex Sight for?

• IPSC and action pistol competitors — requires a direct Shield RMSc footprint and an ultra-light 26 g sight body with a selectable 3 MOA Multi Reticle system to maintain fast slide cycling and instant sight tracking on slimline handguns.
• Hunters and tactical shooters — requires a compact micro reflex dot sight featuring a 21 mm objective lens, 1 MOA per click adjustments, and up to 50,000 hours runtime for low-profile mounting on Weaver or Picatinny rails.

Less suitable for: Long-range precision target shooting or hunting beyond standard non-magnified reflex distances (past 100 m); a magnified riflescope or dedicated prism optic is better suited for long-distance target identification and shot placement.
