And barrel lug is similar to G19 so it’s compatible too
These barrels are not compatible with G17.4 and G34.4OK, I thought the Gen 5 barrels were slightly different and would not work in previous Glocks, or perhaps I have it the other way around. That may be it.
At any rate, glad to hear you CAN use barrels interchangeably like this.
This is from another forum so I'm copying and pasting instead of adding the link but information is accurate:OK, I'm confused again now.
