The shots were lower at 7 yards due to the difference in the bore centerline and optic center line being apart. The closer you are ,the more the difference in offset will be apparent. I set the sight to be center of dot at 7 yards and set the target dot at 12 o'clock on top of the optic sight at 20 yards. Especially if using a larger moa dot. KnifeMaker
I can only imagine this customer's where your solution was making a video walkthrough of his red dot's instruction manual. "see you next tuesday" indeed
I went out again this weekend with my mr920 Elite and no warm up 10 yards 8 out of 10 and the 2 misses were my fault we’re in the bullseye or on the line a a semi rapid pace I LOVE THIS PISTOL!!!!!!!! Holosun green dot forgot to mention !!!!!
I just bought my XR920, and I'm mounting a RMR to it. These instructional videos are invaluable to me as a new pistol red dot shooter! Thanks for helping us old guys and new shooters out.
When you move from 15 yards to 7 yards the shots will arrive lower than your aim point because the of the height delta from the barrel to red dot. If you're gap between the red dot and barrel is about 1 inch, then if you zero at 15, and the 7 yard group is within 0.5 inches I'd call it good.
Hello and thank you,do you co witness the red dot with the sites on the hand gun to start the zero process or use a laser boresight bullet at 25 yards Thank you
If you all are up for some viewer suggestion(s) for next Technical Tuesday: Glock compatible parts on the MR920 - sights? - slides? - trigger housing pins (which gen/backstrap option needed?) - barrels? - triggers? - etc... Proprietary parts (non-compatible parts): - magwell? - backstrap - glock rear cover slide plate? (Do you guys offer a half-cut "armorer's" slide cover plate?) - etc... Other viewers feel free to chime in on what you would want to see!
The mr920 is compatible with all glock gen 3-4 parts. They use a proprietary magewell and bagstrap system that allows you to change grip angle, so those are the only two things I can think of that aren't. The cover plate for the optic cut is proprietary also, but everything else I believe is gen 3-4 compatible
Hey Trever, Thanks for making this video I requested last week. I really do appreciate it as a new red dot shooter and a new Shadow Systems Customer. I'm glad you read the comment section. I did have one other question for possibly a future product. Would your company ever consider making the MR9"20" into ambidextrous Slide Lock and Mag release? I'm an ambidextrous shooter, but I do have slight better groupings left handed. I can do this on my Glock 19 easily.
Love my MR920. G R E A T pistol. I Will outfit my family with them. This comment is probably unwanted, but using a pen to connect each group and mark it (1,2,3, etc) will alleviate confusion when trying to zero. Thanks for this pistol and thanks for the very useable video!
Thank you, Trever. Would you kindly let me know where you were placing the red dot when you were zeroing in your pistol? (That is, in the center of the optic, below the target, or on the front sight, etc.)
Hi Trever, Do I need to change my factory front & rear sights when using red dot on my pistol or does it depend on the make or model of red dot. Pistol would be G48. Thanks for any info. Great video.
Hi Michael, the answer to that question is...it depends. Keep in mind, the red dot is an independent sighting system; you don’t actually “need” iron sights. But most shooters choose to have iron sights as a back up. Those sights can be “co-witnessed” through the glass-the idea is that if the dot fails, you can still use the iron sights. If your stock sights are tall enough to see over the body of the sight, you don’t need to change anything. If, however, your optic cut doesn’t mount the sight low enough to look over it with the sights, and you want a co-witness, you will need to replace the irons. Not all optics are the same height so it does depend on what you choose. For example, an RMR has a lower profile body than a Delta Point Pro-so sights that co-witness with the RMR might not with the Delta Point Pro. Hope that helps. Trevor
Hi Benedict. It should like the mount is not parallel to the barrel and you have run out of internal adjustment within the optic. This might be a question you have to refer to the manufacturer of the mount. Sorry we can't be more helpful.
A little late to the discussion. Assume your Glock was shooting to point of aim with iron sights. With the Glock MOS system you use the #2 plate. You must use the small screws that come with the plate package and NOT the screws that hold down the factory cover. They should rest slightly below the surface of the plate when installed. If you use the screws that came with the cover the optic will not seat properly. Place the Holosun on the plate over the front posts of the plate. It should sit flat with no space between the sight and the plate as the plate should not have space between it and the slide. Use the short screws provided by Holosun. The long ones are for the Picatinny rail. If you use the long ones it can raise the rear of the optic aiming the sight down causing the point of impact to be high. If you used the long ones it may have also have bent the plate, optic or both. If the installation is correct the only other options other than shooter error are bad optic or bad milling of the slide. Hope this helps if in time.
Why my 507k adjustment is reversed? When I click the R should click for right but it goes opposite to the left? And when I click U direction up, it goes down. Can’t figure it out
This can create some confusion if you are looking at the dot and reporting the direction the DOT moves. The screws move the impact of the bullet, which his the opposite movement for the dot itself in the window. For example, if you are aiming at the center of the target with the dot, but the rounds are hitting to the left, turning the adjustment screw in the R direction moves the shots to the RIGHT. The sight accomplishes that by moving the dot to the LEFT. With the dot biased to the left from where it was before, the shooter places the adjusted dot on the target. In so doing, the pistol is being moved to the right which moves the shots to the right from where they were before and they hit the point of aim location.
I noticed the last round the slide didn't lock back. Using pmags? I've switched to mainly glock mags for that very reason. Thank you so much for making these shadow system guns possible to buy at such a great price. Definitely perfection more so then others who claim it right out of the box 👊 👍
I think he had one more in the pipe - looked like he grabbed 6 from the box but shot 5? Edit: Yup - 6 in, 5 out (watch him grab them from the box). Good thing proper trigger discipline was used 👍
Great job on the video. So here’s a question. If you started out with the red dot in the middle of the site…. The next steps you moved the dot 4 clicks to the right and 4 clicks up. So that just moved your dot out of the middle. The. You moved it (adjusted) it again to the right or something… So long story short now I’m guessing it’s not anywhere in the center anymore. So am i thinking about that the right way? You’ve been moving the dot every time away from the middle
I had the same thoughts when I first started using a red dot, Coloin Noir has a video where he is learning how to use a red dot, should be easy to find. One of the drills he had was putting the red dot on target then using his head to move the red dot to upper left, right, down, center etc, you don't need to have the red dot in center of window. Once its zero is to the red dot, where the dot is, is where the bullet goes. It is a good drill to do because you learn too not have to have the dot dead in the center. I think that is what you where getting at? I'm no expert but this helped me learning it does not work the same as a scope.
Most of the approved optics will give a generous lower 1/3 cowitness. The exception is the Delta Point Pro, which has such a tall optic body that there is no cowitness.
Hi Rock, yes 15 yards seems the right distance for most folks. It is far enough to reveal the true vertical position of the group (which you might not see at 7 yds), most people can shoot a good group at 15 (harder at 25--maybe too much variation), and a zero at 15 gives you reasonable poa vs. poi spread out to as far as you might shoot a pistol. Shoot safe!
The Holosun on my War Poet shifted dramatically after my first shots on the break-in session. And... of course.... I left the sight adjustment tool at home. D'OH!
....... maybe? I got busy and haven't even cleaned it. I want to work on just irons for a while til I figure out for sure which backstrap I want, then I'll work on the red dot zero. Feel sorry for me, I have to fire an awesome gun to figure it out. :D
Hi if a red dot is zeroed for 25 yards and i shoot closer then that where will the shots land higher or lower thanks new to red dot as you probably can tell lol
I got a viper for my 920 and I was wondering with the lock screws that get covered when installed, will it stay sighted if I take it off to tighten them down and put it back on.
Agree that this is a challenge with the Vortex Viper. It is possible that it will not repeat when you reinstall the optic or it may take some trial and error to get it positioned identically back on the slide.
@@ShadowSystemsCorp and this is one of the reasons why I went with the Holosun with the battery tray on ;the side. No need to remove the sight for battery change. KnifeMaker
Not to be that guy, but bullets are always supposed to impact the berm. Adjust the height at your target so you're not hitting the ground and possibly skipping rounds over the berm
Take out human error. He mentions that he will often test his zero standing and adjust if necessary, but for initial zero a rested position seems to work best. Then adjust from there if necessary.
Dammit boy 😂😂😂.... you're probably jerking the trigger ..steady trigger pull to the rear let the shot surprise you.. of it scared the shit out of you you did it right
Loved your short and precise explanation on sighting. Now (lol) being the guy that does a lot of target stand maintaining at my local club, I noticed the target stands downrange from your target. These should be removed before firing. Know your target and what is beyond, always.
I wish more company's would make MOS and threaded barrel friendly holsters. I'm looking mostly at you alien gear. Yes I've said this to them. But if someone like Trevor called them up and said hey let's do this thing maybe just maybe they would listen and start on it sooner. Either way I can't wait to hit the range!
"Make sure you use a decent quality ammunition uhhh you know don't zero with total garbage you should wanna you should try to confirm your zero with the ammunition that you actually shoot." But I actually shoot garbage ammuntion 😢
I love how this company makes these videos to help . Thanks and I love your product.

So you do not lightly tap the red dot after adjusting like you should when adjusting a scope before shooting?
I have a question when shooting with a red dot do we have to shoot with both eyes open or close one eye like aiming down the iron sights
purchased glock 43x gen 5 mos & holosun 507k. what is the best iron sights - truglo/ameriglo night sights for co-witnessing
Recommended brand of 3 MOA to 6 MOA Optic for your DR slide cuts for best fit, ease in presentation picture, and accuracy?
I like to rest my entire forearm from elbow to wrist on a table/bench. Eliminates even more movement.
Derek, I do that sometimes too! It does seem like having more of your body in contact is helpful. Trevor

How far do you recommend zero? I’ve seen some people say 15yd and other say 25yd.
Where can one get the coyote brown holosun at and which model is it 407 or 507? Trying to match the color of my mr920.

Thank you, Trever. Would you kindly let me know where you were placing the red dot when you were zeroing in your pistol? (That is, in the center of the optic, below the target, or on the front sight, etc.)
You put the dot on the target. The location of the dot in the housing only matters at close range, otherwise just be consistent.
Just got a mr920L. When are you going to make. G48 version?
