Glock G20

Glock · Gen 5 MOS · Introduced 2023

Glock lists the G20 Gen5 MOS as a Standard 10mm Auto Safe Action pistol with a 15-round standard magazine and an optic-ready slide.

Scope note: Glock lists the G20's current generation only in MOS configuration, recorded here as the base record (decision 2026-08-11); the Gen4 and SF pages remain separate listings. Glock's own page is inconsistent about the name: its browser title reads "G20 V MOS" while its heading, breadcrumb and body read "G20 Gen5 MOS". This record follows the heading. Optional magazine capacities are not listed.

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 G20 Gen 5 MOS?

The Glock G20 Gen 5 MOS is chambered in 10mm Auto. Ammunition should match the exact chambering marked on the firearm.

02How many rounds does the Glock G20 Gen 5 MOS hold?

Glock lists a 15-round standard magazine for the G20 Gen 5 MOS. Glock lists no optional capacities for this record. These are magazine capacities; a round carried in the chamber is not counted here.

03What is the barrel length of the Glock G20 Gen 5 MOS?

Glock lists a barrel length of 117 mm / 4.61 in.

04What are the dimensions of the Glock G20 Gen 5 MOS?

Glock publishes 205 × 35 × 140 mm / 8.07 × 1.38 × 5.51 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 G20 Gen 5 MOS weigh?

Glock publishes 715 g / 25.22 oz without a magazine; 805 g / 28.4 oz with an empty magazine fitted. These are different measurement conditions and are not interchangeable.

06What size class is the Glock G20 Gen 5 MOS?

Glock lists the G20 Gen 5 MOS as Standard. This directory normalizes that to its full-size frame class, so records from different makers can be grouped; the manufacturer's own wording is kept alongside it.

07Is the Glock G20 Gen 5 MOS striker-fired?

Glock publishes "Safe Action" as its own name for the action and does not classify an ignition type for the G20 Gen 5 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 G20 Gen 5 MOS?

Glock lists 26 N / ≈5.85 lb. A published figure is a specification rather than a measurement of any individual firearm.

09When was the Glock G20 Gen 5 MOS introduced?

2023, 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 G20 Gen 5 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.
