Heckler & Koch USP9 Compact (V1)

SEE THE hk-usp9 RECORD for the shared reasoning — Web Archive sourcing because hk-usa.com serves a Cloudflare interstitial, why heckler-koch.com cannot substitute, and why the ignition and operating system are footnoted to the archived manual rather than to the product page. NO WEIGHT IS RECORDED, AND THAT IS THE MOST IMPORTANT THING ON THIS RECORD. HK's weight table gives two columns, "Without magazine" and "With empty magazine", and for this pistol they read 770 g / 27.20 oz and 727 g / 1.60 lb. A pistol cannot weigh LESS with a magazine in it than without one, so at least one of those cells is wrong and HK's table does not say which. Both are internally consistent in their own units (770 g is 27.16 oz; 1.60 lb is 726 g), so the usual tell is absent. Two further observations sharpen the problem without resolving it: the 770 g figure is byte-identical to the FULL-SIZE USP9's without-magazine weight on the sibling page, which would be surprising for a pistol 22 mm shorter with a 17 mm shorter barrel; and the same second column is visibly broken on that full-size page too, where it is headed "Magazine" and gives a 770 g magazine for the 9 mm and 830 g for the .40 against a sensible 98.9 g for the .45. So the defect is systematic across HK's weight columns rather than a single slip, and it is not clear which column survives it. The archived operator's manual cannot arbitrate: its specification table carries Model, Caliber, Capacity, Sights, Width and Height only — no weight, no length, no barrel length. **With two published figures that cannot both be true and nothing to break the tie, the honest output is no weight at all**, the Shadow Systems MR920 outcome. What would resolve it: any HK document publishing one weight for this configuration, or a newer capture whose table has been corrected. THE METRIC OVERALL HEIGHT IS THIS DIRECTORY'S CONVERSION BECAUSE HK'S CELL IS EMPTY. The 9 mm row of the dimension table reads "173 mm 6.81 in. [blank] mm 5.00 in. 35 mm 1.38 in. ..." — the height's metric value is simply missing, while the .40 row above it gives 127 mm for the same 5.00 in. The 127 mm here is derived from HK's own published 5.00 in with the standard helper and flagged, NOT carried across from the .40 row; that it lands on the same figure the .40 row prints is corroboration rather than the source, and the distinction matters because carrying a value between caliber rows is exactly what the USP45 record refused. HK's manual separately prints 127.5 mm for this measurement, half a millimetre away, and is not used. A CONFLICT BETWEEN THE PAGE AND THE MANUAL ON WIDTH, RESOLVED BY INTERNAL CONSISTENCY. The product page gives 35 mm / 1.38 in, which reconciles exactly. The manual's table gives 1.14 in / 34 mm, which does not — 1.14 in is 29 mm. The manual's table is unreliable in that column generally: it prints 1.26 in / 38 mm for the full-size USP9, where 1.26 in is 32 mm, and gives the USP45's height as "5.55 in / 1.41 mm". The page's figure is recorded and the manual's is disclosed. **A document that supplies one axis authoritatively can be wrong on another** — the manual settles this record's operating system and cannot be trusted for its widths. Trigger action and capacity follow the SKU as on the other USP records: the spec row reads "SA/DA, DAO" and "10/13 Rounds" without designating either, and 81000329 is the V1 double-action/single-action configuration with two 13-round magazines. The V7 LEM configurations and the night-sight configurations are separate listings, as are the .40 and .45 Compacts, whose rows differ — the .45 Compact is 180 mm long with an 8-round magazine. Trigger pull is HK's 20 N (SA) and 51 N (DA), newtons published and pounds converted. Frame class is unset: HK publishes no size class, and "Compact" here is part of the model name rather than a class label — the same call as Colt's "Government". Year introduced is unrecorded, as on the other USP records. CORRECTED 2026-08-13, SAME DAY: an earlier version of this note said the manual's warranty section "carries exclusions the warranty PAGE does not state". That was wrong, and it was wrong for a familiar reason — the claim rested on an incomplete read of the page rather than on a search of it. The warranty page carries both exclusions verbatim and the manual simply reproduces the same text. They are now recorded in the warranty field on all six HK records, footnoted to the warranty page, which is where they actually live. Had the original claim been true, folding them in under `warrantySource: "warranty"` would have credited the page with terms only the manual states — the misattribution this directory has now hit five times — and for the VP9 and CC9 it would have been worse still, since the USP manual does not cover those models and neither record cites a manual at all. **The check that caught it cost one grep.** Also published and unrecorded for want of a schema field: a 135 mm / 5.31 in sight radius, a polygonal bore profile, a fibre-reinforced polymer frame, a patented recoil reduction system, and the $1,149 MSRP.
