Why take a nice compact pistol and put a big lump on it?
Well first, the location of that "lump" won't compromise concealability or comfort.
The red dot removes the need to align a back sight with a front sight while also keeping eyes on the threat. Managing 3 focal planes under high stress in a defensive situation is a complicated ordeal. Most people experience some level of double vision while doing this which is why we naturally close one eye to aim.
If you've ever had to defend yourself, you know how difficult it is to remove your eyes from the attacker, and you know how quickly things happen.
So with a red dot, you're afforded the ability to easily maintain both eyes open while looking through and past the optic at the threat. While doing so, you maintain an unlimited field of view and there's no blurred or double vision. The gun, optic, and your hands mostly disappear from your field of view and all you see is the threat with a red dot on it, as if your aiming a laser. There’s virtually no parallax either which means you don't have to line up anything or center anything, especially at defensive distances.
The problem with an actual laser is that the dot easily disappears on certian colors of clothing, especially in bright light situations. With a quality optic, the dot will be visible in all scenarios.
So, in summary you can:
- Maintain threat focus with both eyes open and unlimited field of view
- Get on target more quickly (once proficient)
- Achieve accurate follow up shots more quickly
DO NOT add a dot optic to your primary carry gun as there is a learning curve to get use to .
This is extremely good advice.
