Guns Listing ID: 568465
Quick overview / role
Model: Glock 27 Gen4
Caliber: .40 S&W
Role: Subcompact duty / deep-concealment / backup pistol — “baby .40" for users who want .40 performance in the smallest practical Glock frame.
Why people pick it: Very concealable, rugged, accepts larger Glock .40 mags for range use, and benefits from Gen4 ergonomic upgrades.
What “Gen4" brings
Generation 4 Glock-wide refinements applied to the G27 include:
Modular backstrap system (small/medium/large) to tune grip circumference.
Dual recoil-spring assembly (two-piece) designed to reduce perceived recoil and extend spring life.
Enlarged, reversible magazine catch for faster reloads and left-hand setups.
More aggressive grip texture & revised frame geometry for better purchase.
Finger grooves are present on many Gen4 small-frame runs (some runs differ) — a matter of personal preference.
Representative factory specifications (Gen4)
(Models and production runs vary — these are commonly listed, representative numbers.)
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) (varies slightly by finish/springs/mag)
Sights: Factory three-dot dovetail sights (many owners upgrade to low-profile or tritium night sights)
Accessory rail: None on the standard G27 (no dust-cover rail)
Trigger: Glock Safe Action striker system (factory geometry — consistent across Glock models)
Note: Exact published values can vary by production run — tell me if you want the precise factory spec sheet and I’ll fetch it.
Controls & ergonomics
Grip & fit: Short grip; the flush 9-round magazine gives minimal pinky purchase. Backstraps allow circumference tuning; many owners use extended magazines or +2 baseplates for better purchase at the range.
Magazine release: Enlarged and reversible (Gen4) — easier to activate and configurable for lefties.
Slide stop / takedown: Standard Glock layout and takedown procedure (field-strip identical to other Glocks).
Finger grooves: Present on many Gen4 pistols; some shooters like them, others prefer Gen5’s no-groove approach.
Concealability: Excellent — G27 is very compact for deep concealment, pocket carry, or ankle backup.
Magazines & ammunition
Factory mags: Flush-fit 9-round magazines standard in many jurisdictions.
Extended mags: G27 accepts larger .40 Glock mags (e.g., G23 13-round mags will fit and extend below the grip) — useful for range/duty. Aftermarket +2 baseplates and extension options exist.
Ammo: Use quality factory .40 S&W loads — FMJ for practice, reputable JHP for defensive carry. Subcompacts can be a bit more sensitive to bullet profile and overall length; test your defensive ammo (multiple mags) in the specific pistol before trusting it for carry.
