Trigger Laser Compatible for Glock 17/19 Gen 3-5 & 22/23/31/32 Gen 3-4 & 9X/44/45, Not Fits Glock 22/23/31/32 Gen 5, Compact Green Laser Sight with Power Indicator, WLS-104G

Attached it to my glock and I love it. I haven't used it yet but I'm excited. A few reviews mentioned the battery not lasting long but it came with an additional so we will see how it goes.

I like it a lot. Great attachment for my Glock 23 gen 3

I’ve used the Warriorland Tigger Laser for client pitches over the past month and it’s been stellar. Bright and Crisp green dot, easy to activate button, and it fits comfortably in my hand. The battery life has exceeded expectations — I’ve used it several times a week and haven’t swapped batteries yet.

I wish I could return it, but the window closed. It absolutely gobbles batteries!! Worst I have ever seen. You use it once on the range, maybe ten minutes. Couple of weeks later, it shows “low battery “ when turned on. It dies a few minutes later. Unfortunately I bought two of these due to the excellent fit on the Glock 17 and 19. Big mistake! I now carry a stack of fresh batteries with me to the range, knowing these will fail quickly. I took them off the Home defense Glock due to this problem. Stay away from this failure.

Battery easy to replace with screw cap, Large green dot, not small. (Glock 19.) Laser installed easy in less than 1 minute, slide on rail and tighten 3 screws.

To be fair there are defective products that make it to customers. The specific laser I have is very difficult to have aligned with the gun.

I loved the packing of this product, the laser itself it's very easy to put on ans very easy to calibrate. Highly recommend, I used in a glock 19

This product was easy to install and looks great on my weapon I would recommend this product for your firearm
