Question: Can the TLR-4 be used on a Glock XDS?
Document: When I received the Streamlight TLR-4, I quickly realized it did not fit the handgun for which it was purchased. The light & laser were both outstanding quality, it was the bracket accessory did forced me to return the product. If the manufacture requested the model number of the gun, they would have better furnished the correct assembly. The return process was simple, I received a full refund.
I have this product five stars (well I really want 4.5) because of it's simplicity of use, installation, and overall brightness and power. I have a Full Size USP .45 (which is stated for anyone who purchases this) and installed it onto the piccany rail. However, when I first put it on, I put it semi-tight, but after a few rounds down the range, this has gotten loose due to the kickback from the gun itself.
I have used many Streamlight products and have come to expect a pretty high level of quality and workmanship with their stuff. This item continues my trust in Streamlight and works as I expected it to, after reading many reviews on Amazon. Only issue I had was the lack of rail keys with this particular model, and that was my own fault for not reading that keys were not supplied with this model, clearly explained on the narrative describing the item.
got this for a friend ,they could believe the price there happy with it.got it fast was happy to help someone
When shooting rounds, the lead dust will cover your light and laser. I hope they will make some kind of guard to limit the debris down a bit.Anyways bottom line, amazing product- recommend it to anyone and everyone.
Well built product and works well. great price for the product also. no 5 star bcuz it didnt fit my full size 45 perfectly
The left side gives you personally time to leave it on or off, in which sometimes I put my left thumb (I'm a right hand shooter) and place it on the left side so I can disorient anyone by flashing the bright light.
Once again, not an issue for me since it does not move the dot very much at all and well within the margin of acceptable error for my purposes. When the weather becomes tolerable I'll take the weapon to the range and determine how the light/laser stands up to recoil, which is ultimately the telling test.
Now, I can't ever get it off. I usually soak my handguns in soappy water to give it a good toothbrush scrub under water to free heavy debris, but unfortunetly I cannot do that anymore.Now about the product-There switch allows for 3 settings - Laser / Light / Laser+Light. I have tested this at night outside, the light is super bright, something Streamlight is known for.
Not a big deal to me. The light/laser fits just like it is supposed to fit, adjusts as described in the instructions and I was able to zero the laser to coincide with my optical scope at 52 yards, precisely where I want it. Having read that some folks had issues with stripping the laser adjustment screws, I proceeded with due caution and "coaxed" the initial movement of same so as to avoid any such problems. It worked!
Answer: yes
