Amazing training tool and vastly superior to dry fire - also integrates with Laser Academy etc.
Just wow
Great
These guys went above and beyond for my Wife's last minute Christmas present. Mainly because as a 'man' I can not read a calendar.
She was thrilled! Great product, Awesome service
This system is really just decent at most. After all my uses, hassles and frustrations, if I could go back in time—I would not purchase this again. It’s all fun and joy when it’s working properly, but that’s the thing…it hardly works perfectly all the time. It’s actually quite disappointing when you feel like you got it going but then it just gimps out on you. I find my problem tends to be the very frequent need to replace the striker tips; I feel once my striker tip is a bit worn the whole system becomes fragile and don’t give the same feel. Well, I figure I’d just load up on the plastic tips that really shouldn’t cost more than a dollar. CoolFire charges $10 for a restock, which I can get by but then charges $15 for shipping. So expect to fork up roughly a 10% cost of your overall system frequently to have to running decently or else it’ll sit in a drawer like mine waiting for some third party to 3D print a solution and be reasonable with their shipping charges.

5 Stars — Great Way to Practice More
I loved the CoolFire Trainer from the moment I started using it and saw immediate benefits. I shoot mostly GPA and am still at the beginner level, but I already feel like it’s helping with my muzzle control, aim, and overall consistency.
The recoil isn’t exactly the same as the roughly 800 fps loads I normally shoot through my Glock 22, but it’s close enough to make practice feel meaningful and, more importantly, helps reinforce a strong shooting foundation without having to be at the range.
I went with the extended shot laser. It takes a little fiddling to get it aligned properly, but once set up, it works great. The extended barrel also fits nicely in my open-end holster, so I can practice my draw and presentation as well.
Overall, I’m very happy with it. It’s a great way to get in a lot more quality practice at home and work on the fundamentals. 5 stars — highly recommended.
I think it's great! Ran in to early issues (no wash to help line up the adapter to the barrel but they were sent out as soon as I contacted Coolfire). I'm currently having issues with filling and number of shots (went from 40 to 15). Working to fix...just haven't had the time to troubleshoot. But I love it and it's a worth while training tool!
Excellent
some of the best customer service i’ve had. they were quick friendly and helpful. thanks.
Awesome!
Phenomenal product easy to use. I have definitely recomended this to my friends and family
Great training tool. Safe and I can now train anywhere with my own gun, safely.
Works great and it will definitely help with my training.
Rapid filament, responsive quality customer service, and life changing for consistent low cost development of skills (trigger control, target transitions, recoil management, etc.)
So far I really Like it. This will save quite a bit on ammo and range fees and travel to practice more often. Never neglect live fire though. One suggested tweak for future releases on the laser, it may stay lit too long and draws a vertical line, not a dot on my initial testing. Also, it may have been my one hand casual shooting to see how it looked.
Awesome training tool. Works very well. Just wish I knew to buy extra stiker tips when I got this to save on shipping. Also nothing says what size to get. Other than that the tool is amazing.
Awesome laser. If you’re buying the G43x barrel, this is the laser to get.
Critical backup for your gear
