Shadow Systems MR920

Shadow Systems · MR920

Shadow Systems lists the MR920 as a compact 9 mm pistol designed to work with existing Glock 19 holsters, magazines and gear, with a match-grade spiral-fluted barrel, a factory optic cut and a flat-faced aluminium trigger.

Scope note: THE ONLY RECORD IN THE DIRECTORY WHOSE MEASUREMENTS ARE NOT THE MANUFACTURER'S.

Shadow Systems publishes no dimensions, weight or capacity anywhere — its MR920 pages carry a feature description and nothing else, checked on both the current product page and the 2020 model landing page (read via Web Archive; shadowsystemscorp.com serves a Cloudflare challenge to direct fetching, which this directory does not attempt to defeat). Recorded on a user decision (2026-08-12) that a lower-tier dimension set is acceptable for an explicitly named configuration. The configuration is the standard MR920 with a 4 in non-threaded barrel, black polymer frame and a 15-round magazine — the gun American Rifleman reviewed hands-on. Threaded, Elite, Foundation and Combat variants are separate listings under the base-model rule. Provenance differs by field and every value is tier-labeled on the page: dimensions, weight, capacity, barrel and sights are EDITORIAL, from that review; the trigger pull and warranty are MANUFACTURER. Two disclosures about the lower-tier evidence. First, the retailer listings corroborate overall length, weight and capacity exactly, but Grice attaches the same 7.125 in overall length to a 4.5 in THREADED variant, which cannot be true of both guns — retailers here are evidently repeating one spec sheet across configurations, so their agreement is weak corroboration and the recorded figures follow the review's 4 in gun only. Second, overall width is unrecorded: no source that could be loaded publishes it, and the search-result figure of 1.25 in was never traced to a page. The trigger pull is Shadow Systems' own published 4.5–5.0 lb range, read from the MR920 Elite SS-1012 listing since that is the only reachable manufacturer page — it may not hold across trims, and the review's independently measured 4 lb 13 oz falls inside it but is a measured value the source policy forbids recording. Action type is unrecorded: Shadow Systems describes none, and the review's "recoil-operated" describes the operating system where this directory's other records use ignition type (striker-fired, SAO), so recording it would put two different axes in one column. Warranty is 5 years and fully transferable, read from a 2019 capture because the live warranty page is challenged too — re-check before relying on it. All imperial-only, so every metric value is converted and flagged.

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, Retailer / distributor, Editorial. 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 Shadow Systems MR920?

The Shadow Systems MR920 is chambered in 9x19mm Parabellum. Ammunition should match the exact chambering marked on the firearm.

02How many rounds does the Shadow Systems MR920 hold?

03What is the barrel length of the Shadow Systems MR920?

Shadow Systems lists a barrel length of ≈101.6 mm / 4 in.

04What are the dimensions of the Shadow Systems MR920?

Shadow Systems publishes ≈length 181, height 120.6 mm / length 7.125, height 4.75 in (height: magazine state not stated by the source; width not published). Any measurement basis shown is the manufacturer's own qualifier; where none is shown, the manufacturer states none.

05How much does the Shadow Systems MR920 weigh?

Shadow Systems publishes ≈610 g / 21.5 oz (magazine state not stated by the source).

06What size class is the Shadow Systems MR920?

07What is the trigger pull on the Shadow Systems MR920?

Shadow Systems lists ≈20–22.2 N / 4.5–5 lb. A published figure is a specification rather than a measurement of any individual firearm.

08Does the Shadow Systems MR920 have a warranty?

Shadow Systems states: Five years from original purchase against defects in materials and workmanship, fully transferable. Terms are as published at the date this record was checked and may vary by region.
