Glock 19X Coming January 22, 2018

[call_me_ski]

All generations of Glock 19 have interchangeable barrels. Glock 17 Gen 5 pistols have unique barrels and will not interchange with generations 1-4. They now feature a Glock 19 locking block. I am uncertain about compatibility of gen 5 26 or 34 pistol barrels and prior generations.

AFAIK, all the Gen 5 G19-type barrels, to include the 19X barrel, should work fine in prior generation Glocks. I do not believe the slides are interchangeable between 3, 4, and 5/19X.

Thank you for the info

I can 100% confirm that Glock 19 barrels interchange. I installed my KKM Precision threaded barrel and comp from my Gen 3 Glock 19 into my new 19X. Starting a new Roland Special. It shoots fantastic. So far I have shot about 400 rounds of full house duty ammo. I’ve shot SPEER 124 +P Gold Dots, and Federal +P+ 124’s. Not so much as a hiccup from the combo.
I put the 19X barrel into my Gen 3 19 that has the Unity Tactical slide and the Trijicom RMR. It has been flawless as well.
The KKM barrel and comp shoots “Holy $hit” soft. Super fast and FLAT. I’m likely going to mill my slide on my 19X and turn that into another Roland Special type. This 19X is my new (newest) favorite. REALLY enjoying it. I know it’s the gun the internet loves to hate on, but I think it is incredible.
