Have you thanked a competition shooter lately? You should, because they’re the reason your carry gun has a red dot sight on it.
The competition world of firearms has been an avenue for pressure testing shooting efficiencies for a long time. Accuracy, durability, off/odd angle, use around objects, variable range, all have a discipline where the gear and shooter efficiencies can be tried and evalutated.
Now not everything in the competitive world makes it to the tactical, but there is usually a variant that does if it works in the competition world. Hand gun red dots are an excellent example. LPVOs are another. Although Delta had the short dot developed, one of the major factors that drove them further into the operational sphere was their use in 2-gun and 3-gun. The Razor II’s with the JM-1 reticle are competition built optics the migrated to combat, not the other direction.
