Leupold DeltaPoint Micro Sight

I admit it, like many others when I first saw this sight introduced by Leupold I though it was a 'gimmick range toy' thing. Then one day on the range I saw someone using one, asked her about it and she handed me her gun and said "try it out." So I took a few shots and started to pass the gun back to her and she said "No, I mean really try it out, fire a couple of magazines to get the idea" and she told me some things about it to use it so I fired a few mags and it clicked and I realized it was not a 'gimmick range toy' thing and decided to get one.I got this sight in May 2023, for Glock. Been testing it out since. It has been a sturdy and dependable sight.As I do with any electronic sighting system I put on my defensive firearms, I ran it through a battery of tests like I do when I might have some doubts as to its integrity because the thing is really small.1. I froze it in a block of ice, and kept it that way in the freezer for 5 days. Let it thaw and dry out, the sight still worked after being thawed out. But in looking through the block of ice it was frozen in I could catch sight of a very dim dot (I had turned the brightness up all the way before freezing it to make this easier to see), so it was still working even while still in the ice once I jostled it around to activate the motion sensor although the dot did seem a little dimmer than the highest setting brightness but after thawing out the brightness was back.2. I heated it in a small desktop sized oven I use for testing purposes (of a type that might be used in a lab someplace, not like the type you cook in) - 100 °F for 5 hours. Still worked after.3. Dropped it several times from 30 feet height onto a concrete pad. Scratched up some but still works. I was afraid I might break the glass doing this but it did not break. However, I did take precautions for only the glass and placed a circle of gorilla tape over the glass just in case it landed in such a fashion that might place more force on the glass and there were small dings around the tube at the glass points.4. Dropped it in the pool deep end, eight feet of water, left it there for three days. Had an issue here at first. There is this very thin O ring that seals the battery compartment when you screw on the battery cap. It turns out, if you screw the battery cap down very snugly against this O ring it can sometimes cause it to break. I had given the battery cap a good final twist down against this O ring and it did break which left a small gap for possible water ingress. So I had to delay doing this water test, contacted Leupold and they sent me three free replacements. Then after replacing the O ring I processed with the test. After three days I pulled it out of the pool and it still worked, no water in the sight. But some advice here, you don't really need to apply a lot of force to get the sealing so just screw it down until you feel a slight change in resistance which will be when you encounter the O ring and then just a little bit past that point. Also, make sure this O ring is seated properly before you screw the battery cap down as if its not it can twist and bunch up and break. If I had one suggestion to Leupold for this it would be to not have such a thin O ring.5. Mounted it on a Glock. Zero'd it, then after zero and several magazines proceeded to beat it with a three pound block of hard polymer material (like that stuff quality polymer picatinny rail sections are made from) trying to make it lose zero. It held zero.6. I removed the slide with sight mounted, and froze the whole thing in a block of ice for 5 days. Let it thaw out and dry completely then remounted the slide back on the gun and fired it and the sight had held its zero.And there were some other abusive and mean things I did to it, for example, chucked it down range as hard as I could and against a wall as hard as I could about 15 times, its scratched and dinged (covered those with a Birchwood Casey 'bluing' kit for aluminum) but it keeps working and holds zero.Its held zero ever since the tests, while on the range and firing the gun and has never failed to function. This is on my EDC, I previously had a Holosun red dot on it with a dovetail mount plate. I have moved from that Holosun to using this on my EDC after I discovered that after some 'acquaintance time' and getting used to it I was actually faster for putting rounds on target than I was with my Holosun, plus the Holosun sort of dug into me a little sometimes when carrying concealed and the Leupold DeltaPoint Micro doesn't. So I'm faster with it, not a great amount faster, but having been involved with actually having to fire my firearm for actual self and home and others defense I can tell you a small amount of time can make a big difference when all the time you have is maybe an eye blink moment in time.Now, all this said. There is a 'Ghost Ring' vibe to this sight. I have used ghost rings on on some of my handguns before so its use to put rounds on target fast is not foreign to me. If I turn the sight off, and use just the ghost ring aspect I can place what would be 'stopping/disabling' hits on a man sized target out to 15 yards very quickly. The dot though, that makes it even better and faster for me.Overall though, I love it.

Good quality product, innovative design, and very good support from the company. I bought this optic to attach to a pistol for pocket carry when I discovered that due to macular degeneration I could no longer see my iron sights. It is extremely low profile, and thanks to the enclosed design, durable. The optic lines up on a target like iron sights, so presentation is natural for someone used to iron sights on a pistol. But because of the small window, it is slower to acquire the dot than with a normal sized red dot, though.I'm sad to say that I believe that it will always be a little slower than a normal red dot to acquire a sight picture. Some Operaters out there will cry, "proper presentation!", but I believe that the need for self defense doesn't always happen when both your hands are free and you are square on with a target. However, I have discovered that the enclosure tube of the red dot is small enough to work as a reliable ghost ring sight for close-up targets. With medium and long distance targets, I believe one can spend the extra tenth of a second to acquire a proper sight picture. The good news is that this sight is incredible at medium to long distances, and I regularly ring bells at distances that I gave up trying to attempt years ago with iron sights. I heartily recommend this optic to anyone with elderly eyes for range use, and I recommend it to anyone for defensive use if they understand the above caveats.This is a top quality innovative optic, with unique strengths and weaknesses. You decide if it is right for you.

Mounted this on a Gen5 G17. As an acquaintance snidely put it, it sort of looks like the creature from the movie Alien, when the newly hatched infant creature attached itself to its sacrificial human host. I dunno about that, but it does take some getting used to from an aesthetic standpoint. No RMR here, or DeltaPoint Pro for that matter. So far it works, and does it well. However I am concerned about how much play the adjustment pots for both elevation and windage are. There are no adjustment setting detents at all for tactile 1/4" or 1/2" per click adjustments....because there ain't no clicks. The pots turn smoothly, and alarmingly loosely with little resistance in travel. But so far both elevation and windage settings have held fairly well though I keep having the feeling that this probably won't last. In other words, those adjustment pots don't inspire a lot of confidence.However I can only realistically judge on what the Micro has done so far, and so far I like how it's performed. It comes up much more naturally on the draw, with little to no motion/muscular modification adjustment by me over how I normally sight with regular open sights on the pistol. With a typical reflex red dot optic like a Trijicon RMR or Holosun HS507c with the appropriate adapter plate on the firearm, I have to draw quite differently to compensate for those sights' higher viewing plane or line compared to traditional open iron sights (or plastic, as what's typically supplied by Glock from the factory). That's what has driven me nuts about red dots mounted to a G19 or G23. Decades of shooting those have forever tailored my draw such that adjusting for the higher viewing plane of an RMR or HS507c on an MOS version of the G17 kinda sucks. It doesn't feel second-nature anymore. The draw become conscious again, when before without a reflex optic the draw action was more or less automatic. Trying to teach this old dog a new trick hasn't been easy, at least as far as Glocks are concered.Not so with the DeltaPoint Micro. Its sighting plane nearly matches the sighting plane of open sights. Little to no physical readjustment of how I bring the pistol out of the holster is needed, unlike how I suffer whenever I use one of my Glock MOSes with a RMR-style reflex optic. The Glock with the Micro on board comes up out of the holster far more closely to what I'm used to when I'm using regular factory/aftermarket open sights. Instinctive drawing is suddenly back on the table again.More rounds need to be pushed through this pistol to see if this particular Micro will hold up over time to punishment inherent with slide cycling. However I now have the new SCS MOS sight from Holosun, which allows for direct mounting to a MOS Glock slide without any need for an adapter plate, thereby lowering the optic down to the regular open sight targeting plane. Furthermore Holosun greatly reduced the rim height of the SCS which brings the sight window to be much closer to the slide...and the pistol's regular open sights. No suppressor height cowitnessing necessary. And more importantly to me, a much more familiar "muscle memory" draw with the pistol. Which means that I probably won't shoot the OTHER Glock 17 with the Leupold Micro nearly as much...because in the end it's still weird-looking. Not a great reason I admit, but the SCS looks more 'regular', and the Micro just doesn't.Still, I'm so far guardedly impressed by the performance of the DeltaPoint Micro. The adjustment pots still feel like they can be a weakness but so far that hasn't shown itself to actually be that. If it ever does show itself in that manner, then it's a case of "I told myself so" and that I should've just sent it back. But I haven't and I won't. It's a Leupold after all, and I'm very much a fan of their optics. Only time will tell if they got this one right, and I'm willing to give it a serious try...as long as the new Holosun SCS will give me enough time (and ammo) to properly vet it out. 4 stars so far.
