Glock G40

Glock · Gen 4 MOS · Introduced 2015

Glock lists the G40 Gen4 in MOS Configuration as a Long Slide 10mm Auto Safe Action pistol with a 153 mm barrel and a 15-round standard magazine, presented for 10mm shooters and handgun hunters. The directory normalizes its frame class as long-slide.

Scope note: Glock lists this model only in MOS configuration — g40-gen4-mos is its sole product page, and the sitemap holds no non-MOS G40 — so the MOS page is recorded as the base record under the 2026-08-11 decision.

The page's heading reads "GLOCK 40 Gen4 in MOS Configuration" while its title and header chip read "G40 Gen4 MOS"; the generation is recorded as Gen 4 MOS. Year introduced comes from the January 2015 release announcing the MOS platform, preserved only as a Web Archive capture: it announces the G34, G35 and G41 Gen4 MOS as released and the G40 as "coming soon", so 2015 is the year Glock announced the model, not necessarily the year it shipped. No later manufacturer source gives a ship date. The manual's spec table (p. 59) matches the product page on every recorded value. At 915 g without a magazine this is the heaviest record in the directory.

Verification boundary: Published technical data are rounded, may not reflect manufacturing tolerances, and may change without notice. MSRP is not recorded: most cited product pages do publish a price, but it changes without notice and independently of the specification, so this directory has no field for it and the row stays blank rather than carrying a figure that would silently go stale. Values marked ≈ were converted by this directory from the unit system the source published; the unmarked figure in the same row is the published one.
Evidence tiers backing this record: Manufacturer. Unmarked values come from manufacturer documentation; any value drawn from a lower tier is labeled inline with that tier. Where two sources disagreed, the higher tier was recorded and the disagreement noted.

Common questions

Answered from this record's cited fields only. Where a manufacturer publishes nothing on a subject, the question is not asked rather than answered with a blank.

01What caliber is the Glock G40 Gen 4 MOS?

The Glock G40 Gen 4 MOS is chambered in 10mm Auto. Ammunition should match the exact chambering marked on the firearm.

02How many rounds does the Glock G40 Gen 4 MOS hold?

Glock lists a 15-round standard magazine for the G40 Gen 4 MOS. Glock also lists 10-round capacity as optional. These are magazine capacities; a round carried in the chamber is not counted here.

03What is the barrel length of the Glock G40 Gen 4 MOS?

Glock lists a barrel length of 153 mm / 6.02 in.

04What are the dimensions of the Glock G40 Gen 4 MOS?

Glock publishes 241 × 34 × 139 mm / 9.49 × 1.34 × 5.47 in (height: including magazine). Any measurement basis shown is the manufacturer's own qualifier; where none is shown, the manufacturer states none.

05How much does the Glock G40 Gen 4 MOS weigh?

Glock publishes 915 g / 32.28 oz without a magazine; 1005 g / 35.45 oz with an empty magazine fitted. These are different measurement conditions and are not interchangeable.

06What size class is the Glock G40 Gen 4 MOS?

Glock lists the G40 Gen 4 MOS as Long Slide, and this directory records the same class.

07Is the Glock G40 Gen 4 MOS striker-fired?

Glock publishes "Safe Action" as its own name for the action and does not classify an ignition type for the G40 Gen 4 MOS. This directory records the manufacturer's wording and leaves the ignition field empty rather than inferring a classification the source does not state.

08What is the trigger pull on the Glock G40 Gen 4 MOS?

Glock lists 24 N / ≈5.4 lb. A published figure is a specification rather than a measurement of any individual firearm.

09When was the Glock G40 Gen 4 MOS introduced?

2015, per the source cited on this record. Where a manufacturer publishes no dated announcement, this directory records no year rather than estimating one.

10Does the Glock G40 Gen 4 MOS have a warranty?

Glock states: One year from original purchase by the initial consumer; regional terms apply. Terms are as published at the date this record was checked and may vary by region.
