Pistol Red Dot - BUIS in front of or behind the optic?

[Franko]

I'm dipping my toes into red dots for the first time and looking for feedback.

Thanks for reading.

I prefer the rear BUIS in front of the optic if possible. As shown on my rusty project bedside gat.

Unless you have experienced both situations, in-front v. behind, you won't know which is best for you.
I prefer the sight in front of the optic whenever the slide geometry dimensions allow it.

Placing the rear iron sight in front of the optic has a number of advantages:

• It deflects debris and burnt power residue from hitting or coating the optic
• During one-handed clearing exercises, you are putting pressure against the iron sight and not your expensive optic
• It allows a clearer, larger field of view
• Red dot and rear iron sight act as a single unit instead of two separate ones that the eyes have to align

I prefer in the front. I don't want anything getting in the way of the window or to detract my focus. I want to see the dot/window first.

Buy an optic made in the USA or another free country, and get one that is duty rated (Trijicon, Leupold, Aimpoint, etc). Avoid buying a Holoson optic because they are a Chinese communist entity. China has control of enough industries, we don't need to help them gain more. The fact most of us are typing on Chinese devices, keyboards, is a perfect example of WHY we need to make a stand regarding our sport and companies not being further undermined by the Chinese.

Try to have the iron sights appear through the very bottom of the glass so they don't obscure the optic's window- lowest possible co-witness.

I thought I wanted "suppressor height" sights so I could see them thru my red dot. What a load of internet BS. I bought a fancy red dot to put a little light on things I want to go pop. Not have something obstructing my view. I tried it with both heights. This was behind the red dot not in front.

FULL/Absolute co-witness is when the sights are in line with the center of the window and Dot- and full co-witness has been losing popularity because that decreases the view and quick acquisition of the Dot- which is the whole point of a Pistol Mounted Optic- clean draw and presentation of pistol and Dot appears over intended target... Having sights fully co-witnessed makes that tougher. Lower third or lower quarter co-witness is much more common now because it keeps the sights low and the view cleaner.

Yeah it was lower 1/3 and it was still too much. I could see that if the irons were mounted in front of the red dot, my eyes might not have gravitated towards the irons so much.

Thanks all. Going to go with the sights in front of the optic (closer to the ejection port) and with low co-witness sights.

I don't bother with co-witnessed sights any more. Once your index is solid you can use the optic's window frame to smash COM hits out to 15 yards with decent speed.

But I also only trust Trijicon products for this application.
