    Glock barrel

    This is a great product. The add I received said it was $100.00 on black Friday. Turned out it was 30% off. So it still was a good deal at that price. I love it. The comp is great. I am going to get another one for my 43.

    Perfect fit. Made a big difference in felt recoil. Especially with weak hand unassisted.

    Excellent product that noticeably reduced recoil. The fit and function was perfect, and I hope they make this for the .40 and .45 caliber.

    Barrel with mini comp

    Published by G Boy on 5th Jun 2019

    Installed this on a Gen 4 Glock 19. The gun has a tungsten guide rod, so the recoil is less than a stock Glock 19. After the installation, I noticed a significant reduction in the recoil that I would estimate at 25-30%. I hope they make this for the .40 and .45 caliber as this is a winner!
