Drop-in 9mm replacement barrel for Glock 19 Gen 1-3 pistols and Polymer80 PF940C builds. Cut to factory OEM dimensions so it slips into any standard Glock 19 slide without fitting work — ideal as a stock-barrel replacement or as a build component for stripped slides.

Frame and Slide Compatibility

Fits Glock 19 Gen 1-3 slides and any Glock 19-pattern aftermarket slide cut to OEM spec. Not compatible with ported slides unless paired with a ported barrel.

Finish

416R stainless steel, vibratory-finished. Unbranded — clean profile for builds where you do not want a maker mark on the hood.

Specs

• Caliber: 9mm Luger
• Twist: 1:16
• Rifling: button rifled, conventional land-and-groove
• Material: 416R stainless steel
• Pressure rating: P-rated for full-pressure 9mm
• Length: factory Glock 19 spec (4.02")

Run the first 100-200 rounds with quality FMJ to seat the barrel before grouping with carry ammunition. Verify your slide is Glock 19 Gen 1-3 spec before ordering — Gen 4/5 dimensions are slightly different and this barrel is not cut for those slides.
