Overview / role

Model: Glock 23 Gen5

Caliber: .40 S&W

Platform / footprint: Compact Glock frame (same general footprint as the Glock 19 family)

Intended use: Compact duty/concealed carry/backup with greater terminal energy than a 9mm compact; common with law enforcement and civilians who prefer .40 S&W in a compact package.

What Gen5 changed (key Gen5 differences from earlier Gens)

Generation 5 introduced a number of design and ergonomic changes intended to improve reliability, ambidexterity, and shooter fit:

No finger grooves — smoother frontstrap (finger grooves removed for a more universal fit).

Ambidextrous slide stop lever — slide stop is present on both sides for left/right-handed operation.

Flared magwell on many models (some production runs/models) — helps faster reloads.

nDLC / improved slide finish on later Gen5 slides for better corrosion/wear resistance (finish varies by production run).

Marksman Barrel (GMB) — Gen5 pistols commonly ship with Glock’s Marksman Barrel: enhanced rifling and tighter tolerances intended to improve accuracy.

No chamfered slide rails / changes to internal geometry — internal refinements aimed at reliability and parts life (not user-serviceable improvements).

Different recoil spring assembly (single-piece guide spring vs Gen4 dual-spring assembly — Glock standardized spring systems across some Gen5 models).

Improved extractor & feed ramp polishing on many factory runs (production improvements rather than a single explicit user-change).

Other small dimensional/tolerance changes intended to make the pistol more consistent and more optic-ready overall (but factory MOS is still a separate option).

Representative factory specifications (Gen5 G23)

(Manufacturers publish exact specs; the below are standard values commonly listed for Glock 23 Gen5.)

Caliber: .40 S&W

Magazine capacity (standard factory): 13 + 1

Barrel length: 4.02 in (102 mm)

Overall length: 7.28 in (185 mm)

Height (w/ magazine): 5.04 in (128 mm)

Width: 1.34 in (34 mm)

Weight (unloaded): approximately 25.06 oz (˜710 g) (varies slightly by finish and accessories)

Sights: factory three-dot sights (steel or polymer depending on run); dovetail-mounted — many owners fit tritium or low-profile sights.

Slide finish: nDLC or equivalent on many Gen5 runs; older Gen5s may have Tenifer/other finishes depending on production date.

Frame: polymer with steel inserts, modular backstrap not present (Gen4 had modular backstraps; Gen5 removed finger grooves but kept refined ergonomics).

Trigger: Glock Safe Action (striker-fired, three passive safeties).

Accessory rail: standard Glock rail for lights/lasers on the dust cover.

Optics: Gen5 G23s are not automatically MOS-cut — look for factory MOS variants or have slide milled by a qualified armorer if you want an optic.
