    Can I use a threaded barrel intended for a G19 in my G45 ? I haven't taken the time to even look into this. I do know my G45 upper will function on my G32 lower, but I don't know if it is a "proper" fit.

    So who has the 411 on the barrels of the five generations ?

    I have used a Generation 4 threaded barrel of my Glock 19 in my Glock 19X. The G45 is the same gun.

    It will work.[​IMG][​IMG]

    I have shot my Glock 19X suppressed.

    Thank you sir! Exactly what I wanted to hear. Your 19 is bad ass. Tastefully done without being overboard.

    For G19/19X/45 yes it should be fine, but not for G17 Gen 4 to Gen 5.

    My LW threaded barrel works fine in my Gen 2 G19 and my Glock 45...
