Seems like everyone uses 23s. What's the differences between them?
|
Generally, the G19 and the G23 are identical, except for the size of the hole in the end of the slide that the barrel goes through... its bigger in the .40 Glocks.
The
aftermarket 9mm barrels have the same outside diameter as the OEM .40 barrels, so they fit properly/tightly.
You
can not run a OEM Glock-brand 9mm barrel in a .40 Glock, its too loose/sloppy at the muzzle.
