Train Smarter with Realistic Recoil—Using Your Own Glock 19

Take your dry-fire training to the next level with the CoolFire Trainer Barrel for the Glock 19. Unlike traditional dry fire, the CoolFire Trainer uses CO₂ to cycle your slide and simulate recoil, allowing you to practice faster follow-up shots, trigger control, sight tracking, and target transitions—all with your own firearm.

Whether you're a competitive shooter, law enforcement officer, military professional, or responsibly armed citizen, the CoolFire Trainer helps you build real-world skills without the cost of ammunition or frequent trips to the range.

  • Practice safely at home without live ammunition.
  • Reduce training costs while increasing the frequency of your practice sessions.
  • Compatible with our Red or IR laser for interactive target practice (sold separately).
  • Designed for thousands of training repetitions to help reinforce consistent performance.

What's Included

  • CoolFire Trainer Barrel
  • Replacement Recoil Spring Assembly
  • Storage Pouch

Train More. Improve Faster.

The best training tool is the one you'll use consistently. By adding realistic recoil and interactive feedback, the CoolFire Trainer transforms routine dry-fire practice into an engaging experience you'll look forward to. More enjoyable training leads to more repetitions, better habits, and greater confidence every time you shoot.

Spend less time driving to the range and more time refining the fundamentals that matter most.

It fit in the gun perfectly and functioned well right out of the box. The recoil was very realistic.

Sig Sauer P226 CoolFire Trainer Barrel

I am returning my Coolfire/MantisX Package as it wasn't what I expected, and admittedly my expectations were probably unrealistic. I am still giving 5 STARS due to the professionalism and support CoolFire's customer service team has provided me. A company is only as strong as those who are running it and dealing with customers and CoolFire is a strong one.

Laser worked as expected. Very bright

The quality is first rate and well made. I was really surprised with the realistic recoil that it generated. While it is not as much as shooting live ammo it is very very close. Using it with laser targets makes for great practice when you can't get to the range.

Sig Sauer P320 Full CoolFire Trainer Barrel

Excellent service. Arrived promptly. I purchased the 5 inch 9mm barrel for my S&W M&P 2.0 metal frame. Everything I read on the internet and AI said the barrel wouldn't work in the metal frame model. I spoke with customer service and they said it would work as there is an adjustment on the barrel. They were right it worked and it is a very good product in my opinion.

It was easy to install and use with my mantis x elite

Good recoil, however it still misses the front vector force to make it more realistic, it is great to practice

Absolutely awesome! What a game changer. The recoil add and trigger reset encourages me to practice more. Quality set up!

Glock 17 CoolFire Trainer Barrel

Extremely satisfied with the AR-15 SideKick. I was already a superfan for my handgun CoolFire. This is simply more of the same goodness for my carbine. This will up your dry fire training game, make it more enjoyable, more realistic, and drive you to do it more often. Ten minutes a day of CoolFire training is a game changer, seriously.

Just as described love it as close to the real thing as you can get

It’s amazing! I love being able to practice in my own home with my own pistol. I get live feedback on exactly what I’m doing right and what I’m doing wrong.

Bryan Morris
CoolFire Trainer MantisX Package

This is one of the best trainers I have ever used. Having the recoil is what makes this a great trainer.
