I have found it listed as both 4.01 and 4.49 inches so I suggest that you call Glock to be sure Phone: 770-432-1202

Th G17's have the longer barrel at 4.49 inches. I hope you were able to get it figured out!

The barrel is absolutely 4.49 inches on all G17's Jason unless threaded. Any listing for 4" is incorrect.

Specs on the Gen 4 G-17 show a 4.49 inch barrel. The G19 has the 4 inch barrel.
