TLR-6 Rail (Smith & Wesson M&P™) with white LED and red laser. Includes two CR 1/3N lithium batteries

This fits the 9m full size, M&P, S&W like a glove. Easy quick install, quality parts, and simple laser sighting. It looks like it came with the pistol. Amazon has holsters to fit with the light/laser attached as well. The light is extremely bright and effective for its purposes. A light-weighted product as well. I also like the fact that its black. Upon use of the pistol with the light/laser, the assembly didn't come loose. Further testing might be needed. I might add that after removal, the product did not leave any marks on the pistol.

Brightness is as advertised and not the best, but considering this is for a pistol and you're only going to have an effective range of 25 yards at most, it does the job just fine. The laser is bright enough and easy to spot even in daylight, and it was easy, albeit not simple, to slap on the attachment and get the batter fit in, but that's perfectly fine considering how compact it is, plus it just makes my pistol look cooler! Overall the product didn't fall short in anything advertised, and is pretty well constructed!

This fits beautifully on my M&P 2.0 (full size). Love it. One reviewer stated that this didn't fit their gun of the same size and model, but you can see in the pic they posted that they didn't install it properly...which kind of blows my mind. Haha. It took me 5 minutes to install it.

There are no instructions. If you're used to installing pistol attachments this will be a breeze. If not, you need to look at it and take your time. It becomes intuitive to adjust the laser after a bit. Cycling between light, light/laser, and laser isn't described but easy enough to figure out.

I reviewed several other popular brand’s flashlights and lasers for my S&W M&P9c, but none of them had this flashlight/laser combo together and they didn’t look nearly as nice as this does when attached to your firearm. The flashlight is definitely the most important feature of this tactical flashlight/laser light in my opinion, but having a red dot laser incorporated into the same attachment is definitely a plus! It’s super easy to attach/mount to your firearm, taking less than 5 minutes, and it’s even easier to operate. It has a button on both the left and right side of the attachment that allows you to push the button with your index finger in order to turn the flashlight/laser on and off regardless if you’re right or left handed. It has three modes of operation: flashlight only, red dot laser only, or flashlight and red dot laser together. Each mode can be changed by pressing both the left and right buttons at the same time. The placement of where the button is located on the side is perfect for where your index finger normally rests when holding your firearm. Adjusting the red dot laser is relatively simple as well. You just use the included Allen wrench and turn each screw (one located on the bottom, which adjusts the vertical alignment, and the other on the side, which adjusts the horizontal alignment) clockwise/counter-clockwise. It’s always best to align your laser light while at the range so you can gauge the accuracy of it, but of course you can use any of the popular brand laser bullets to also help with accurately sighting in your laser light. I used the popular brand Boresighters while at the range to ensure best accuracy. Another convenient feature is the fact that the batteries are supplied with it, so no need to purchase any batteries just yet. I highly recommend this Streamlight for everyone looking to add either a flashlight and/or laser light attachment to their firearm. The flashlight is very bright and the red dot laser is very easy to see. This attachment doesn’t add any extra weight or different feel to my firearm in my opinion, and I love the tactical look of my firearm as well now. Another positive aspect of this attachment is that several popular gun and holster companies make standard and custom holsters for the S&W M&P9c with TLR-6 attachment. A couple popular companies that I used when purchasing a holster for my S&W MP9c with TLR-6 attachment was Dara Holsters for my kydex holster and Alien Gear Holsters for my adjustable/mountable holsters. In comparison to Streamlight’s competitors, the price is unbeatable and more than reasonable for what you get with the attachment. You can’t go wrong with this attachment, and you will definitely love the look and feel of your firearm.
