Owners of the GX4 3.0 with the blue PVD slide pick it for the color-matched look alongside the practical subcompact 9mm format. The PVD coating holds its finish reasonably well under regular carry use, though the high-contrast blue shows wear more obviously than a standard black slide.

Shooters praise the 13-round capacity for a pistol this small, and the overall feel in the hand is considered comfortable relative to other subcompacts. The trigger is functional but a common discussion point among owners, with many noting it improves after break-in while others find it underwhelming compared to competitors at the same price.

The GX4 at this price point competes well on value, and owners generally report reliable feeding with quality 9mm ammunition. The blue PVD version gets repeat comments about looking sharp while still being a working pistol, though a few owners note the finish scratches from kydex holsters faster than they expected.
