I would like to share my experience with the Cool Fire Trainer for my Glock17 Gen3.
I was looking for good dry fire posibilities for my Glock (private and duty) for a long time. In the last couple of months the desire to get something that enhances the training capabilities with my Glock grew extensively.
A friend has a SIRT pistol and an AR15 SIRT bolt and he combined everything with L.A.S.R. and I was able to test those devices. While I really liked L.A.S.R. I could not warm to SIRT (I am talking about the pistol now). I wanted to train with MY pistol, MY sights, MY grip and MY trigger.
So I did a research for systems that are at least able to reset the trigger of my Glock. But I was not satisfied with things that are available. By chance I got word from Cool Fire Trainer System. I thought it was expensive but the desire for a good training tool was bigger. So I bought one.
BLUF: I do not regret it at all! For me it is currently the best dry fire tool I can think of (price-performance ratio).
When the order was still on it´s way I found the video with the negative comment that is posted above. I thought "fuck! I have just ditched 400 dollars!". But all the panic was for nothing. If you see that the spring does not fit because it is to long and still put it together and fire it... .
The first shots with the Cool Fire kit already impressed me a lot. It is awesome to feel the recoil and to be able to pull YOUR Glock trigger over and over again! It is hard to describe the actual recoil. But I would say it is about up to 70 % of the real one. Perhaps a bit less and a bit different. But it is enough to get your sights off the target and enough that you have to grasp the gun thoroughly. The laser that you screw into the barrel was perfectly zeroed. Meanwhile (after about 4000 shots) I had to re-zero it. Not a big thing. A small downside of the laser is that it gets activated by jolt. That means that it gets also activated when the bolt closes. With full CO2 you will not see it. But when the systems slows down you will see 2 laser spots. One for the hit and one after the recoil. But that does not bother me. Apparently it does work with L.A.S.R. though. But I think you would need their special webcam. I will try that in the future.
I still got the old version that does not come with the little exchangeable plastic caps for the center piston. But they offer to change that piston.
The whole system works really well. When the CO2 barrel comes loose you just have to put thread locker on it and fix it again. No big deal. The sealings are all exchangeable and you are able to disassembe the whole device.
For refill I bought a CO2 bottle for paintball purposes. It holds about 500 gramms of liquid CO2 (and you need liquid CO2 for proper function!). I put the empty and the filled barrel on the scale. The Glock17 barrel holds about 4 to 5 gramms of CO2. That gives you up to 20 consistent shots. Depending on the speed you shoot it. The faster you shoot the colder it gets. And when it is cold the system looses power. That is a common physically effect. So after a few runs I would recommend to give the system time to warm up again.
Benefits in a nutshell:
- You can train with YOUR gun, YOUR trigger, YOUR grip and YOUR sights.
- Mag change drills are as realistic as they are with live fire. I would buy the system just for that!
- You will train and squeeze the trigger more than ever before. Just get up in the morning, take the system while still in your bed and "fire" a couple of mags at random spots in your room.
- IMO it is a perfect tool for instructing beginners. You do not need a shooting range, eyepro or earpro and the student will get a feeling for the recoil.
- Add laser targets and enhance everything I jsut said above.
Will it harm your Glock? I do not know. But I don´t think so. The piston is made of brass and this is much softer than any part of your Glock. But of course all parts of the pistol move as they do when live fired. But with less force and without heat.
To sum it up I can only say positive things about this system. I will try to get some kits for my unit and I will get a Glock34 System for my Glock 17 as well. The guys from Cool Fire recommended it because the G34 barrel holds more CO2 (for more repetitions) and forces a stronger recoil. The G34 barrel will fit the G17. Of course it will stick out more than the G17 barrel. Even more so with the added laser. Just keep that in mind concerning your holster.
