StormLake for Glock 17 9mm Stainless 5.17'' Ext. Length Threaded Barrel GL-17-9MM-519-01T-T
Machined from certified 416R stainless steel for superior strength, durability, and accuracy.
Barrels are match grade, hardened to 40-42 HRC and cut broach rifled to shoot jacketed or lead bullets.
All barrels are chambered for full case support. All Glock barrels are drop in and will only occasionally require modification to fit. Extended lengths are available, as well as ported and threaded options.
Two port options are extended barrels with ports beyond the end of the slide (available for models 17, 19, 20, 21, 22, 23, 26, 27, 29, 30, 31, 32, 33, 34, 35). Four port options are standard length barrels where all ports are within a slide cutout area - a cutout in the slide is required to accommodate the ports (available for models 17L, 24, 34, 35), or with all ports extended beyond the end of the slide (available for models 20 and 21). Six port options have a combination of the two ports beyond the end of the slide and four ports within the slide cutout area (available for models 34 and 35).
Check with the manufacturer of your attachment to verify thread option before ordering. 40S&W-to-9mm conversion barrels require the use of a 9mm magazine.
