I wanted a laser training aid for dry fire practice. I ordered the g sight laser trainer and received it yesterday. I ordered the .380 model because a lot of reviews recommended it over the 9mm model. There are reported fitment issues with the 9mm model. I gave it a light coat of oil and had zero problems loading it into my G26. It worked great and you can clearly see the laser streaking if you jerk the trigger. That is the exact feedback I was looking for. I can’t speak to the longevity of the product yet but it only cost $40. I spend more than that on a quick range trip. This product also has an app for some kind of drills but I haven’t looked into it yet.
