G19 Barsto Barrel

[py73]

I just recieved a threaded Barsto barrel for my G19. One thing that I've noticed, is that the notch (tongue) on top of the chamber is just a little bit longer than the tongue on the factory barrel causing there to be an equivalently wider gap between the sides of the barrel chamber and the slide. With the factory barrel, there is also a little bit of daylight between the side of the barrel chamber and the slide, but it is an ever so slightly smaller gap.

Is this a problem? (I've fired several mags through and it's cycled fine. However, it has problem cycling wet suppressor--AWC Abraxus.)

Also, is there a reliable Glocksmith in Northern Florida--Tallahassee?
