Gmconn Rechargeable Green/Blue/Red/IR/Purple Beam, Low Profile Beams Compatible with 21MM Rail

I've purchased a lot of these (about 30) for various pistols with rails, mostly the Keltec P17 for friends. Brightness, battery life, size, low weight, reliability, durability, ease of charging is all fine. Attach with one bolt, stays attached ok. I zero them with red bore sighters which unfortunately you have to do fairly often. Zeroing isn't perfect but close enough. I've only broken one by torquing it on too hard. For the price these lasers are great!

*update #2: shot another 150 rounds through it, laser is still holding zero perfectly. I know other reviews have shown people having issues with that and granted I have a .380 but it is certainly not having an issue with me even after over 300 rounds and carrying on s regular basis. Worth buying in my opinion**update: first time shooting with it, held up very well, kept my zero on it after 160 rounds downrange. It’s a keeper, ≈ $40 well spent.*First impressions, this laser/light combo is phenomenal. It’s very compact but very powerful. The construction doesn’t feel cheap at all, it feels pretty sturdy (although of course, range testing will tell more). As for fitment, this fits perfectly on my S&W M&P Shield .380 EZ. Another review shows it pictured on the 9mm version, that fitment is essentially the same for mine and the lighting is fairly accurate to what I experienced with my set up, although pictures don’t give the best showing of light.The laser is super bright, can see it easily in both light and dark (have not tested outside, was inside with lots of lights on and with lights completely out). It was easy to adjust the laser to sight in to exactly where my sights are pointed at 10 yards.The light on it is very bright for a compact combo, it lights up a hallway very well and you can see your sights’ shape enough to aim well when shining it in complete darkness, plus you can see your laser dot in the light when both are activated. The strobe feature is very nice (simply hold the button down to select steady or strobe light, turning on and off will stay on your selected mode so if strobe ain’t your thing you can keep it on steady no problem easily).The convenience of the micro-usb charging is wonderful, no need to deal with and stock batteries. The buttons are also placed at an angle that keeps your holster from pressing them and wasting battery, and the angle makes it easier to press them while gripping your firearm.For the price especially, this laser/light combo is phenomenal. You can’t beat it. I would highly recommend it for anyone who wants this type of attachment on their gun.

Five stars given, in light of the ~$25 or so cost, which makes this kind of amazing.Obviously don't expect this to necessarily outperform a 4 star 3-figure name-brand mil-spec version. And yes, it's a low-cost foreign import with a plastic housing. But really, this thing is pretty remarkable. It's low profile, the flash-light is surprisingly bright. I mean, seriously, it's very good, and brighter than some larger units, but a decent amount. The Green Laser is visible to 50 yards in daylight decently enough, and of course at night, is good for a long long way. I LOVE that it's USB rechargeable, vs taking some goofy exotic and expensive batteries. (The type of which this marketshare will buy the cheap versions of, which are usually just terrible). So having a rechargeable Li battery inside, is fantastic. Also, that means no housing for a battery compartment, meaning you get more power in the same footprint too. I can't comment on its life, as only have a few minutes total run time, but so far so good.I can't comment on how well it holds zero yet, but will say the adjustment screws were not overly loose (a common problem with low budget items of this nature), and actually had a quality feel to it. I also can't comment on how well it will hold onto and stay stiffly mounted, once mounted - I'll learn that with time (typically low-cost units use low-alloy screws that easily stretch and lose tension, and the connection threads are just tapped into the plastic, vs a metal insert, so we shall see on this one; I'm guessing with a second retorque in a week, it'll be serviceable enough). It's made for pistols, but will go on any picatinny rail just fine.As to the plastic housing, I don't actually mind that - not for a $25 unit. It keeps the weight down and also less "clack" when it brushes up against something.I'm seriously thinking of buying a pile of these and throwing them on everything and gifting them. This is a LOT of power and capability, in a small package, for just $25.

Pretty cool little unit. Fit my Byrna SD launcher perfectly. For the money, a great laser sight.

⭐️⭐️⭐️⭐️⭐️ I run these or ones like on almost all of my firearms, from pistols, shotguns to a few long guns. This one was purchased for the wife’s G3C as it’s like the one on another G3C I have. Its size is perfect and it fits the holsters we have for those pistols just fine. The brightness is great on the light and laser both. This is a great tool for any firearm and I definitely it per application usage. Charge time is short and easy to charge. Adjustment zeroing is easy and accurate as well. It functions as it should and we are extremely happy with the purchase!

Great product! Bright laser, bright light that toggles between steady light or strobe..mounts perfectly on the gen 5 Glock 45. It's rechargeable which is awesome! And you seriously can't beat the price. I've put a couple of hundred rounds through it and it still hold true..I make sure the screw is tight..ill probably add a drop of locktite on it. BUY THIS! does the same job as ones that costs as much as the gun. No brainer

Nice laser and flashlight but barley fit.
