Guns Listing ID: 568501



Overview / role

Model: Glock 27

Caliber: .40 S&W

Role: Subcompact concealment / backup / deep-concealment duty pistol — “baby .40." Designed for maximum concealability with decent terminal energy for its size.

Who chooses it: people who want .40 S&W power in the smallest practical Glock frame, or officers needing a very compact backup.

Design & operation

Action: Striker-fired, semi-automatic with Glock’s Safe Action (three passive safeties: trigger safety, firing-pin/firing-pin block, drop safety).

Operating system: Short-recoil, locked-breech (Browning tilting-barrel).

Frame: Polymer with steel chassis/inserts; compact rounded profile for concealment and low snag.

Intended use: Deep concealment, backup, off-body carry, and close-quarters defensive use.

Representative specifications (typical)

(Values vary slightly by generation/production run — these are the common figures.)

Caliber: .40 S&W

Standard magazine capacity: 9 + 1 (flush OEM subcompact magazine)

Barrel length: ˜3.42 in (˜87 mm)

Overall length: ˜6.41 in (˜163 mm)

Height (with magazine): ˜4.17 in (˜106 mm)

Width: ˜1.26 in (˜32 mm)

Unloaded weight: ˜20–22 oz (˜567–624 g) depending on generation and finish

Sights: Factory three-dot dovetail sights; many owners upgrade to low-profile or tritium sights

Accessory rail: None (standard G27 has no dust-cover rail)

Trigger: Glock Safe Action striker system

Generations & notable differences

Gen2 / Gen3: Early standard features; Gen3 added accessory rail on many full-size relatives but G27 remained subcompact shape.

Gen4: Modular backstraps (small/med/large), dual recoil-spring assembly, enlarged reversible magazine release, more aggressive grip texture; finger grooves present on many Gen4 small-frame runs.

Gen5: Removed finger grooves on many models, refined grip geometry and finish (nDLC on many runs), revised internals/tolerances. Availability of Gen5 for G27 depends on production runs — confirm model stamp when buying.

Controls & ergonomics

Grip: Very short—flush magazine leaves little pinky purchase. Backstraps (Gen4) help tune circumference. Many owners prefer extended magazines or +2 baseplates for better purchase.

Magazine release: Standard on older gens; Gen4 introduced a larger reversible release for left-handed operation.

Slide stop / takedown: Standard Glock layout and takedown procedure (field-strip identical to other Glocks).

Concealability: Excellent — one of the smallest practical Glock platforms for everyday deep concealment.

Magazines & ammunition

Factory mags: Flush 9-round magazines are typical OEM.

Extended mags: G27 accepts larger .40 Glock magazines (G23 13-round mags will fit and extend below the grip) — useful for range/duty use. Aftermarket +2 baseplates and extensions available.

Ammo: Quality factory .40 S&W loads — FMJ for practice, reputable JHP for defense. Because subcompacts may be more sensitive to bullet profile and OAL, test your chosen defensive ammo across multiple magazines before relying on it for carry.

Handling, accuracy & performance

Recoil & controllability: .40 S&W in a tiny, light platform is noticeably snappy — sharper impulse and more muzzle flip than larger/ heavier pistols. Gen4 dual-spring softens it somewhat, but expect more training required for fast, accurate follow-ups.

Accuracy: Adequate for defensive ranges (inside ~25 yards). Short sight radius limits precision at longer distances; the G27 is optimized for point-and-shoot self-defense.

Practical performance: Very good for close-quarters defensive use when the shooter trains for the platform’s characteristics.
