How to Choose The Best Red Dot Sight for .45 ACP?

Durability: .45 ACP pistols tend to have more recoil than some other calibers. You'll want a red dot sight that can handle that recoil without losing zero (calibration). Rugged brands like Trijicon RMR Type 2 or Aimpoint Micro H-2 are known for their durability.

Size: Full-size pistols can handle larger red dots, while compact carry pistols might benefit from a smaller, lighter option. Holosun HS507C is a popular choice for its balance of size and features.

Features: Consider features like automatic brightness adjustment, multiple dot sizes, and shake-awake functionality. Some sights, like Holosun models, even offer a circle-dot reticle which can be helpful for some shooters.

Budget: Red dot sights can range from budget-friendly to high-end. Burris FastFire III is a good option for a value-conscious buyer.
