The Glock Marksman Barrel (GMB) improves accuracy and durability over previous generations. The nDLC finish provides scratch and corrosion resistance. Front slide serrations added in Gen 5 allow press-checks and racking without the rear serrations only. The interchangeable backstraps adjust grip circumference for different hand sizes. Three safety systems (trigger, firing pin, and drop safety) operate automatically without a manual safety.

The Glock 17 Gen 5 generates consistently positive feedback from a wide range of shooters, with very few substantive criticisms.

Reliability is the most cited positive. Owners report dependable function across environmental conditions and ammunition types. The Gen 5 ergonomics, particularly the grip texture and ambidextrous slide stop, get specific praise as improvements over earlier generations. Accuracy comes up favorably; users report tight groupings, and the GMB is frequently credited. The 17+1 capacity is seen as ideal for defensive use and competition. The nDLC finish holds up well over time compared to earlier Glock finishes.

Weight comes up as a mild drawback for daily carry, though most accept it as a tradeoff for the full-size capacity. Price occasionally draws comparison to budget alternatives, though most buyers consider it warranted. The Glock ecosystem has extensive aftermarket support for sights, triggers, holsters, and magazines, which is seen as a strong positive by owners who want to customize.
