Difference of scope vs red dot.
Now you have the correct tool for the job at hand, in my opinion.

 

I shot this 5-shot target at 50-yards … with a red dot (Trijicon RMR) on a 44 Special revolver. In general, the red dot isn’t the problem.

Jus, sayin’.

 

May need to check that holosun....

 

I'm not real familiar with the specs of the Holosuns..what was the MOA of the dot itself? some of them are 2, some of them are 6, some of them are 12...it matters

 

12" at 50yd, must be a 24 MOA dot.

 

1MOA red dot on S&W 41 and X22 for old eyes.
Hunting can see having larger MOA on red dot.

Hawke scope on X22 got same tight benched results as 1MOA red dot.
Nature is quantum fuzzy which makes it fun, never boring, and interesting.

 

The Holosun is a 2” dot. It’s always held zero and still does. Nice sight for the money.

 

They are solid optics for the cash,I have one on my .30-.30 and i know they will hold a tighter group than pictured.maybe something wasnt quite right during mounting.

 

Now im not saying youre wrong, so please dont take the following as meant to be offensive or that i think you're wrong, i dont have the rifle in my hands(obviously).heck i havnt even seen a picture of the rig.
If barrel contact is the issue i would imagine that would show up with a scope as well. if thats not the case then i would venture to say it was a bad day, but for S&G'S.. I put my red dots as far foward on the reciever as i can to increase the sight radius Idk where you mounted yours.

 

That’s where I put mine, too. I prefer the Outer Impact mount, lower and quite secure. The issue I’m trying to address is the vertical stringing as the barrel heats up. With a cool barrel, the groups are nice and centered, but after 100 rounds or so, I’m getting a lot of shots high and low, scope or red dot.

 

 

With surpressor i wouldnt be terrible surprised if it starts getting fouled out after XXX round count and starts stringing, without the surpressor id say the barrel would be the weak link. For what its worth from a random dude on the internet.

A Holosun 407C X2 comes with a 2 MOA dot in red or green. The picture you posted does not match the picture for the Holosun 407C on Holosun's website (HE407C-GR X2-Holosun). Part/model numbers don't match and your dot says "Outer Impact" on it.

2 MOA at 50 yds substends 1.05".

You really should read the entire thread before commenting on the accuracy of the OP‘s photo. The OP stated in post #14 that he uses an Outer Impact mount. The optic is clearly marked HS407C X2. Accuracy matters.

I would remove the suppressor, and check for anything touching when firing, or try firing without the suppressor. Something has to be touching with that grouping if sight proves to be ok. There are occasions whereby the suppressor is not installed in line with bore of barrel, and flyers occur. Just an observation from description.
