Red dot optic adjustment

[lexo98]

Today I took out my P365 that I recently installed a Holosun 407K on to the range. Prior to install I took it to the range and hit the target just fine. After firing with the red dot it was obvious it needed to be adjusted and I forgot my tools. However, when firing at the target looking thru the lens (red dot off) using the front sight I was still way off. Does adjusting the red dot change the angle of the lens? Is that why I shot it way better using the front sight without the red dot installed?

Can you see the front AND rear sight through the lens?

What he said above for the irons.

Also with RDS you focus on the target not the dot, makes it much easier to shoot with both eyes open . I start with the target 5-7 yds to adjust the rds as it is much easier to get it close, then walk it out to 25 or so. Sometimes it helps to do an intermediate distance like 15yds to adjust the rds before final adjustment at 25 or so. Nothing wrong with using a rest for initial adjustment and later fine tuning it offhand, also unless you are an expert shot it is best to use 5-10 shot groups and adjust for the center of the group vs trying to use 1 or 2 shot, very easy to get a flyer offhand at 25yds.

I felt like I could see thru the lens just fine. It seems like the lens was changing the angle I could see the front sight at tho. Maybe it?s all in my head.

Maybe I?m using the RDS wrong but I was way off trying to use the irons with the RDS off too. I?ll try your advice next outing. . Thanks

The lens does not change. The reticle is moved when adjusted. The big question that you haven't answered is whether you can see the rear sight and align the front sight with them. That should not change regardless of whether you have an optic attached or not.

Irons and dot should zeroed independently

You should not aim the dot t the irons

Adjusting the red dot changes where the red dot projects on the lens on most red dot sights.
The lens is normally fixed and should not be moving unless you have a C-more where the dot is fixed and the lens is adjusted.

In order to rough-zero the red dot, you only need to rest the gun and adjust the dot so it's sitting on your front sight when you align the iron sights.
After that, you will hold the gun so that the redo dot is well above the irons and on-target.
There's no alignment of the red dot to the irons necessary when actually aiming with the red dot.

Red dot window is not a lens. At least the idea is that it should act as a "piece of glass," with no magnification or parallax (not counting parallax associated with the dot itself).

If you line up iron sights looking at them through the red dot glass, the alignment should be the same as if the glass wasn't there, so you should keep the point of impact. However, it is not clear from the OP whether you can see the rear sight and whether you're aligning the sights the same as when the dot wasn't there.

It may be this.......

The red dot is independent from the front/rear sights. Adjusting the red dot does not move the lens. Adjusting the red dot also does not adjust the iron sights in any way. Towards the rear of the red dot sight, there is a tiny little housing with a light in it, that's the part that moves when you adjust the dot sight. Nothing else moves.

Because the red dot is adjustable, and the front/rear sights are PROBABLY fixed sights (non-adjustable), you may have the situation where the red dot sight to be right on, but the iron sights (front/rear sights) are off a bit. You'll have to find a way to drift the rear sight left/right or other work to get those sighted in.
