The Glock 17C Gen 3 is a full-size semi-automatic pistol chambered in 9mm with a 4.49-inch compensated barrel and a 10-round magazine. The compensated slide has porting cuts to reduce muzzle rise. It ships with a polymer frame, fixed rear sights, and a blue/black finish. This is a California-compliant configuration.

The G17C occupies a narrow niche: buyers who want the full-size Glock 17 platform with factory porting. Most owners note that the ported barrel and slide do reduce felt muzzle flip, particularly during fast follow-up shots. That said, the porting also vents gas upward near the shooter's hand, which some find uncomfortable and which makes suppressor use incompatible.

The fixed sights on the Gen 3 platform draw mixed reviews. Shooters who run the pistol stock appreciate the simplicity, but those used to adjustable or aftermarket sights often swap them early. The Gen 3 frame geometry is well-understood after years of production, and holster compatibility is broad.

The 10-round magazine limit on this variant targets CA-compliant buyers specifically, and owners in standard-capacity states generally pass on it in favor of the 17-round G17. For restricted-market buyers the G17C represents a useful porting option without magazine restrictions in their home state mattering less.
