I have been seeing many ads for SeeAll’s Open Sights and decided to get one to test. Here is their web site and description…


“Mk2 Pistol Sights are a game changer for pistols! SeeAll Sights do not require perfect eye position, and reticle placement is not critical. Simply put the point on your target, and pull the trigger. No modification to your slide is needed to mount a SeeAll. Push out your rear sight, push our dovetail into the existing slot, and mount the sight to the dovetail. It’s that easy, and the money you saved using an existing cut just payed for your SeeAll! Shooting tight groups, and confidence with your handgun is possible, and leave your worries behind you. Once sighted in your SeeAll Sight is ready when you are, no batteries, no electronics, built to hold up, and nothing to turn on. Pistol Sights start at $100. Make your pistol perform the way you envisioned!”

I decided to mount these to a Gen 5 G26 as it was the only Glock that was 1) not my wife’s 2) not regularly carried, 3) still with original factory sights, and I have a Gen 4 to compare it to with night sights.


Although installation was straight forward; replacing the rear sight with a metal mount and then screw in the SeeAll, this proved to be a challenge. As the mount was metal it proved too difficult for the Glock Sight pusher and I had to move up to a more sturdy sight pusher (VISR) and even then it took a fair amount of force to get the sight mount in place (I am not looking forward to getting it out).

Once in, the SeeAll sight attaches with a single screw, and did not seat perfectly flush to the slide. There was a slight upward slant down the muzzle and though it could be pushed down, there was nothing to hold it in place. If you bought this sight and liked it, you would likely want to explore some form of additional adhesive.

Initial Impression/Dry Fire

Working the G26 dry I found it hard to quickly acquire the black triangle and once acquired it was easy to lose it again. I found it worked much better with both eyes open, but still seemed to talk longer to get a sight picture compared to iron sights.

Live Fire Tests

I ran about 50 rounds through the G26 (10 round magazines) at 21 feet ‘zeroing’ in the top of the black triangle. I will say during this process (very slow deliberate accuracy shooting: 3 round groups) I was shooting very tight groups often placing rounds on top of each other. However, the point of impact was a good 3” down and 3” right (testing my aim once with a G26 (Gen 4 with iron night sights) it was not me J. It took about 5-6 groups to get the triangle on target. I then rounded out the breaking in shooting small groups alternating both eyes open and using my dominant eye.

I then ran 5 drills of 10 rounds shooting on signal from high ready (single, controller pairs, double taps, and 3-4 rounds). I compared these to the same drills with the Gen 4. I measured overall 10 round groups and total time for the 10 round group.

Results and Thoughts

I was hoping at $99 and no MOS or machining required that the SeeAll would provide a solid option to get a more ‘advanced’ sights on just about any handgun. Also the no electronics appeals to me as I am very reluctant to use any electronic sights on a carry gun. One of the big advantages of red dots is that for many people the dot is quicker to acquire as a sight picture and reacquire on subsequent shots compared to iron sights. I found the SeeAll triangle to be the reverse of this trend: harder for initial acquisition and follow up reacquisition.

I shot tighter and faster groups with iron sights.

Now part of what is advertised with these sights is the idea that sight to eye alignment is not important and as I stated they worked better with both eyes open. In other words, I think if you trained with these sights you could learn to use them and likely then be quicker than iron sights. But as they function different enough from traditional sight alignment, this might be a steep learning curve for some (me included) and may at the same time reduce traditional sight picture skills. At $99 and adaptability to most handguns these still may be checking out for some, but they did not pass my initial testing and are likely soon to be off to live with the other discarded sights and holster.
