ZBULAR 2 Mile Laser Sights Range Slide Racker Jacker Compatiblewith Glock 17, 19, 19X, 26, PSA Dagger, and More with Improved Slide Grip(Class IIIA Green Laser Output is <5mW)

This is a good product. I was a bit concerned I would hate it because it adds height/bulk to the pistol and could interfere with racking. I actually love it. It is easy to install and zero in (I used a red laser bore sight to do that). It moutns securely and doesn't lose zero after shooting. You can still see the iron sights under it so you can always fall back on those. The laser is bright in day and night. I have no idea how long the battery will last or how to tell if it is getting low. I plan to just charge periodically to ensure it never fails when I need it.

This works well and is easy to attach to the gun. The green laser is bright enough for day or night time use.

I picked this up for my Glock 17, as I prefer to run a green laser on my carry pieces. However, the traditional under the barrel set up does limit holster choices. I figured giving this one a try couldn't hurt.Set is very easy...once you figure out the non-instructions. You simply push the whole laser down on the back end of the slide over the rear sights. The instructions then tell you to tighten the screws. All you can really see is a small Philips screw on each side and the set up didn't include a throw-away driver of that size. Huh... But once you look closer, the screws they are talking about are tiny-tiny hexheads recesses back in holes that could be mistaken for manufacturing marks. It's the same size as the zeroing screws as well.Once I got it snugged, I gave the slide a few hard rapid pulls to test it out and see if it made wracking the gun easier...it did. It did feel a little loose after that, so I retightened it making sure I got all the screws dialed down. That helped a lot.I zeroed this laser using the laser I already had mounted to the bottom as well as a bore sight laser. They were pretty much all on target at the 10 m mark.I ran 100 rounds of standard pressure 115gr target ammo through the gun without any loosening which honestly kind of surprised me. It functioned fine and stayed true.I'm not sure if I'll keep it on my Glock as I kinda like my laser I have on there and I like the holster it works with. However, where I see this set up shining is for those that don't usually carry a laser on their pistol but might want one. I could see this being handy for walking in the woods where drawing and firing on a dangerous critter won't give you much aim time. The green laser is much easier to see in the daylight.. You could keep your same holster set up but throw this on in about 2 minutes. It's intuitive to use and the way it hoods over the sight causes you to really focus on that front blade.

This is a cool new device for a slide without a rail. Connecting this to the slide provides a laser switched on by pressing down on it. The laser also provides a slide racker aid. It gives a taller and large surface area to pull back the slide. Another nice feature is the window just above the base, which allows the sights to be used in cowitness.

Green lasers are amazing. They are so highly visible to the human eye that even in bright sunlight they are easy to see. When they are as bright as this laser is, this goes doubly! I mean this thing is BRIGHT.It attaches firmly to a Glock (pay close attention to the models it says it fits) and holds zero very well.It has a constant-on and flash mode, but honestly the flash mode is so hard to activate, even when NOT in a stressful situation, that it is useless. You simply have to double-press the on/off button too quickly for it to be a reasonable option. The on/off button is very easy to activate once, however, so getting the laser on and getting on target quickly is just a matter of practice.The body is nicely milled from aluminum and is very sturdy. It holds fast to the slide and really does offer a nice upgrade to the grip of the slide.The USB-C rechargeable battery is a very nice plus. It provides so much convenience that you could reasonably carry with the laser on just to keep from having to activate when needed. You would have to experiment yourself with runtime to see if the battery lasts long enough for your needs. If the battery dies on you, the ability to use iron sights under the laser is a very handy feature.The mount makes a firearm a little taller, so this may be an issue when carrying. In my case, however, the extra height is not uncomfortable to me. Your mileage may vary on this, depending on your body shape and carry style.You will NOT be disappointed in the brightness of this laser. Just based on the characteristic alone, this is an amazing sight.

Ordered this primarily due to its flexibility in being able to fit 13 Glock models. Note; Zbular has an additional adapter mount plate shim enclosed in the set not shown in the parts photo description to optionally be used depending on your respective model.The laser is very easy to activate with the push button conveniently located at the rear of the laser.(see photo) Importantly, the laser may be charged while still attached to your slide with the included USB-C charger cable. It easily and securely mounts to your slide and is affixed with three mount screws per side using included wrenches. The laser beam’s focus is simple and quickly adjustable without problem. Best of all, this is an exceptionally bright green laser. (see photo)

I found the build quality to be very nice, and the green laser is very easy to sea.I like how the laser mounts to the top of my Glock, similar to an optical sight, this allowed me to use my current holster without having to find one that accomodated an under the barrel mount.The instructions are a little confusing, but since I have some mechanical know how I personally had no issues mounting it. And so far it looks like it’s going to hold up well to the rapid firing of the pistol but only time will tell if it can handle the banging of the slide over long term. But for right now I really love having this laser on my Glock. I think it’s a great deal for the price.
