UPDATE: DISSAPPOINTED IN LASERLYTEI have had this for a while now, so this is my 2023 update.It was starting to make a plastic squeaking sound, and I decided to take it apart to check out the insides. There are several points where you can stick some silicon grease to make it operate more smoothly.This pistol trainer operates very similar to those laser bullets you put in your gun. A piston hits a switch and that is what activates your laser. Even after all this time, the laser still lines up perfectly with the sights.The components inside the gun are nicely designed! The laser itself sits inside a brass cylinder which has a couple pressure washers holding it in place, there is a metal weight inside the grip for that hefty feel, and the plastic exterior is thick and strong which also held up great!So why am I disappointed? The gun is nice, but is it $200+ for the kit or $100+ nice for the gun itself? No. The price rose substantially since I bought mine, and that is a huge shame. It is going to keep out a bunch of new gun owners from honing their skills and doing it safely with a good product.We could have people practicing with a truly good trainer, that has truly changed my game. But more than doubling the price... it does a disservice to the community. This laser gun is more expensive than some Hi-Points out there.Speaking from my experience translating this trainer to a real gun, if you can shoot and have the laser gun not move at all from where you are aiming AFTER pulling the trigger. You are going to hit exactly where you are aiming with a Glock. But this huge price increase? Come on.ORIGINAL REVIEW: If you are an experienced shooter, this is only midly useful.But if you are a newer shooter or have never been exposed to guns before, this is the next best thing to shooting live rounds.You can practice holster drawing, fast shooting, quick draws, thing which are generally more dangerous. As long as you take any mistakes you make seriously.My biggest issue was flinching and trigger pull, and the only way to really get over the flinch from that boom is to keep exposing yourself to it. Force yourself to open your eyes and feel/see the whole explosion. As for trigger pull, this trainer is perfect for that slow/smooth trigger pull, I'd say it is like shooting my CZ75 with the hammer down. The trigger pull is long and a bit heavy.I noticed my aim improving considerably after practicing with this product. Even my friends don't believe you can improve your aim that much using just a laser gun. But if you master the fundamental basics, the rest kind of follows. I think the two biggest things to good aim is trigger pull and steady hands, and you can practice that safely with this.The pistol feels kind of toy-ish, but the sights are in line with real life. And as a result, I really enjoy using iron sights and shoot best with them. If LaserLyte made a gun which was the same weight and size as a real pistol, it would be perfect! But this does the job, it just doesn't really feel like a real gun.
