How to Zero Your Handgun Red Dot 

2:37 Had me feeling like I was back in Geometry, Lost lol

One of the best videos I've seen on properly zeroing a pistol red dot. You used a rest and an actual sight-in target, and showed the method of adjustment. Good stuff. 👍

Here is the simplified math for the commenters. 1 MOA is a 1" adjustment on target at 100 yards so .1" at 10 yards or .15" with your specific optic. 1 click (on optic) on your windage/elevation= .15" on target or 6.66¯ clicks (on optic) per full inch of target.

I mostly shoot competition for fun/ training, the 10 yard zero would give me issues at 25-30 yards, hitting a bit higher than I'd like for small poppers and such, once I switched to 25 yards, it's point of aim-point of impact from 3 to 25 yards, with my setup at least, apparently other people have different experiences. Great vid, keep doing you.

13:20 I agree with locking the gun down and shooting off 3 rounds and adjust from there because no person has a perfect stiff hold every time. That lock down mechanism WILL hold that gun down perfect each time.

Best red dot zeroing process I've seen yet!! Great job Roger as always!

Thank you so much. I just watched this just before I went to my local indoor range to shoot a handgun with a red dot(green dot actually) for the first time ever and it was with a brand new Springfield Hellcat OSP I just bought this month and a new holosun 407k I just bought as well, and your video help me get it done the right way and now this thing is Zero'd perfectly. Thanks:-)

I just used my iron sights to zero my 407K on my Hellcat Pro. I took it to the range the other day and it was absolutely perfect at 10 yds. No adjustments needed. I know this isn't the best way to zero a dot at distance, but worked great for my needs.

This has to be the best tutorial on how to zero your handgun. Thanks, Roger!

I am new to RDS and this is the best video I have seen on the topic of zeroing. Will do this on my 507K this weekend.

Good instruction. There are always different ways to get to your goal. 10 yard or 25 yards zero, find what works best for yourself. Know you point of aim from 1-50 yards. Running two marks. Red `124 and white 147. Thanks for the video.

I like the lethal weapon smiley face in the head box minus the low left flyer

Great tutorial. I zero at 25 yds. There’s a bit of mechanical offset 7 yds and in and 1+ inch low at 50 yds. I use a black Bull target as there’s greater contrast with Dot for me. I dial in with Carry Ammo and make reference marks with White oil base marking pen, then re/dial with range ammo and make corresponding reference marks with Red marker.

Thanks for the pointers. I’ve always done it free hand or with a sand bag. But this feels to be a far superior method. Thanks again!

I am not a steady enough shot to use the technique taught in the video, so I had to figure out a way that would work for me. I clamped my empty pistol, barrel down, under a light bright enough to see the three iron sights. I held my head so the front sight is properly aligned in the rear sights. My Sig P365XL has combat sights which mean that when aligned this way the bullet will go to the target where the center of the circle on the back side of the front sight is. If a gun uses non-combat sights the target should sit on top of the front sight. Using the adjustment screws on the red dot sight I moved the red dot so that it sits in the center of the front sight, which is where the bullet would go to. Now the bullet will go where the red dot is which is where the iron sights are also aimed. Voila! The red dot is zeroed without wasting any bullets. The results are good when I shoot the target at the range. I am open to any criticisms of this technique.

Awesome video! I’m recently into slide mounted optics on my carry guns and was wondering what way would be best to zero them. My department is looking into red dots as well for our service pistols and I will be forwarding this to the lead instructor as well. Always quality content!

Explained it very well. Thanks for the helping people. Great video.

Great job explaining it. I usually just wing it with no math calculations behind it. Thank you.

Excellent content from Mr Barrera. The Views and subscribers are not indicative of the quality of this channel.

I'm just glad you zero at 10 yards with a pistol like I do. I don't know how these guys zero at 25 yards with a pistol. I'd be at the range all day and probably still not have a legit zero.

I know your skin gets dry living in the desert… Especially this time of year. But COT DAAAMN, Roger!! The sound your hands make every time they touch sounds like the swooshing sounds 90’s windbreakers used to make every time you took a step!! Moisturize them paws baby!! Bill Burr was definitely on to something there..

Great video. The 507 comp is 1MOA not 1.5MOA. 10 clicks at 10 yards according to manual. Correct me if I’m wrong

Really nice video dude, I'm about to buy the same red dot optic. Keep the teaching good job!

Great tutorial! 👍👍 I zeroed mine at 10 yds, then confirmed at 15 & 25 yds to determine hold unders, etc. I mostly shoot indoors & 25 is the max. But, you never know if or when you will need to take that longer shot...

Great video. I got so frustrated chasing my shot I went thru 100 rounds at the range and still not zero 😢

Roger, I’m a retired police chief & current Lt. with the Jefferson County Sheriff’s Department. I purchased my first Staccato (C2) after watching your C2 video…I loved the gun so much, I purchased the CS & I recently purchased the XC, but the XC is the first I’ve purchased with the holosun 509T & Staccato co witnessed the red dot to match the iron sights…qualifying with 100 scores…I recently purchased a Holosun 508T for my C2, but it was bore sighted, I’ve zeroed the sight, but once they added the taller rear sight, Staccato told me to purchase a new 2,65 front post to match the new taller rear sight. When the new front sight is installed, would you recommend co-witnessing with the iron sights, or work on perfecting the zero on the bore sighting that has already been done. Truly value your opinion and any advice would be greatly appreciated!

For me the best tutorial.

Great video, all great advice, thank you for posting this!!!

Love the donut holster. 😍😍

This is the way.

Nicely Presented Brother 🤘🏼

Nice work Roger, you are good at this stuff.

Great video I stand up while zeroing mines but this device looks like it would help out a lot more but going to the range once a week or every two weeks will help with dialing to zero

Love your holsters and your How to videos! LMFAO at the " I'm Asian and love math comment " hahahaha

What about using a bore laser to get close then fine tune after?

Are you putting the dot in the middle of the glass?

Thx for the info Great video Hopefully I can get a optic soon

Great video! Thanks for the tips!

Great Info! THANKS

You need to show way more camera shots thru the optic so we can more easily visualize what you are seeing when you zero. I've seen videos where they center the dot in the optic vs videos where the dot basically co-witnessed the iron sights. What are YOU doing ?

To be fair your target was moving in the wind, but good video it’s my favorite gun

Great video Roger, I’m new to red dots so this was supper helpful. 👍🇺🇸

Awesome content.

Very helpful, thanks

Good information. By the way, I didn't see you at SHOT range day and wanted to see if you still have any leftover QVO SHOT Show 2023 patches. I want to put one on my patch wall.

Thanks for this video.... Helped out alot

What great groupings 😮

Thank you for sharing this knowledge. When I attempt a zero am I slaving the dot on the iron sights? The firing and then making my adjustments? And when I like where I’m at, how come my dot disappears when I line up my iron sight to aim again? Like the dot is almost behind the front irons?? Or am I not doing this correctly? TIA!!

Great content. Very informative

I purchased a gx4 Toro installed a 407k I tried to sight it my first looking at my sights and seeing how far away the Red Dot was. The Red Dot was very far off to the left so I tried to turn the hollow sun to the right but it was as far right as it would go I was going to return the site until I decided what the hell let me turn it to the left so I turned it to the left and the Red Dot came into the right right on my front sight I'll never understand these things I'm too old I guess

“I’m Asian I like math” 💀 🤣

What are your thoughts on zeroing while flinching? While it is obviously better to simply not flinch and pull your shots, but for some who haven't trained out of it, would you say it is better for them to zero it based on it's mechanical zero or it's adjusted zero? Of course who can say if the individual will flinch on the first round when they actually need it.

exactly how i do it, great video brotha!!

First impressions of CS vs C2?

When you start to zero do you put the red dot on the target then zero from there or is it point of impact from your iron sights then zero your red dot it's kind of confusing sorry

Same here, 10 yd zero. 👍🏼

Awesome content! Thanks

Good stuff.

Cool video to put out my guy 😈

Very helpful thank you

One thing I don't understand is that if you are shooting high right. Wouldn't you adjust the red dot to match where you are shooting? In other words, adjusting the red dot up and to the right to match your group? You had said go down and to the left. That part confuses me because I get that it would put your dot on center, but with a bench rest, how would it change where the bullet is going? Please explain. I'm trying to process this. Thank you!!!

Another great video thanks.🤟👏👍😎🇺🇸🇺🇸

"I'm Asian so I love math." Gets math wrong 😅 Thanks for the video!

Thank you for the information. Really enjoy all your videos.

Roger, Bro, EXCELLENT Video!! I also zero my dot’s at 10yds. I know A LOT of folks who zero their dots at 25yds. IMO and for my use I think 10yds is the idea distance to zero. Keep cranking out that content brother! 😎 #RobbArmstrong

Nice job. Question, I google the info you was saying for the adjustment on a red dot couldn’t find it. Could you give me the math problem for it I use a Romeo red dot and I zero at 15 yards. Would save me a lot of headache doing your way. Could you help thanks

Let me apologize for my stupid question upfront, as I don’t understand, red, dots, and sites so much.. when you’re trying to dial in the dot are you trying to place the red/green dot on top of the front sight covering the front sight or are you trying to get the dot lined up with the middle of the glass that is mounted on the slide.?

That's a good one! Thank you!

Are you moving where it's shooting to the red dot or are you moving the red dot to where it's shooting ?

Are you placing red dot on top of front sight post? Or center of the dot in sight window?

This method did NOT work for me when i did my red dot on each of my 3 AR15's ... I adjusted the red dot to where the shot should land and it just threw my shots off even further. The original shot was 3 inches to the left and 2 inches down from the center target where my red dot was. When i adjusted the red dot 3 inches to the right and 2 inches UP, it threw my shots even further away. Now they were 6 inches to the left and 4 inches down. I adjusted the dot again and to find i was not hitting the target at all anymore. So what my brain told me was to put the red dot WHERE the bullet was landing. So i did, and now my red dot is zero'd to within 1 inch.

Have you had a chance to compare the Ultimate Ammunition to the Underwood Xtreme Defenders?

So in a natural stance do you start with the dot in line with the front sight post?

I have the same optic. If i zero at 20 yards how many clicks for 1 inch?

Do you initially move the dot to roughly the center of the window? And what about the irons. Are they lined up in the window? Or perhaps the front sight is slightly above the plane?

Where can I find the carry ammo I’m having trouble locating it

HEYYYYOOOOOO!!!!!!!

Great video. What bench rest are you using

Great video

507comp is 1moa adjustments not 1.5, just as an FYI.

Really enjoyed this. Please continue to more training/ teaching lessons more frequently

With a 10 yd zero what is your POA/POI offset at 25 and back?

Good Vid.

Good shit!!

I’m shooting a Glock 21, 45 ACP, Federal 230 grain FMJ. Optic is a Holosun HS507C-X2-ACSS Vulcan. The difference between 25 and 15 yard zero (no 10 yard targets at my range) is abut 4 inches. Is that me or 45 ACP?

Do I use the front site with the red dot. Or just the red dot?

Good stuff

T rex arms has free targets as well

Holosun 508T 1 MOA perclick Zero at 15 yard 1 in = ? click

Carry is sig 365 color is red and random number is 5

Now that its zero , will u be on target if you shoot that same target at 50 or even 100 yards out? Or are you going to be off be alot?

When CS video?

👍

Roger, this question has nothing to do with this video LOL. What ear pro are you running? The Axil GS 2.0? Fan of them if so? I'm in AZ and muffs are brutal during the summer. Don't want to pay $600+ for custom molded in ear.

Can I use any 1inch grid target for zeroing at 10 yards?

Outstanding

Most shooters need to work on their grip and shooting finger way more than having a perfectly zero'd pistol. Close enough is good for me for self defense

Boy that baby is jumpy!

What range are you at? I live in the Las Vegas area and would love to head into that range so that I can do zeroing and target shooting.

What range is this in Las Vegas?
