  1. Gregory P.

    I recently purchased the barrel/comp combo for my Glock 45 and must say the fit and finish is top notch. Mixed with a tungsten guide rod my G45 is quite the flat shooter. I’m very happy with my purchase and hope you soon manufacture a barrel/comp combo for the G43x. Thanks for an excellent product and I will be doing business with you in the future.

    Perfect!! Comp is bad to the bone

  3. Jason G.

    Great barrel and comp. Fits great into my aftermarket slide and timberwolf frame.
    The only negative thing is the comp keeps coming loose even with the supplied rockset
