SEE THE hk-usp9 RECORD for the reasoning this one shares with it: why the sources are Web Archive captures (hk-usa.com serves a Cloudflare interstitial to every request), why heckler-koch.com cannot substitute, why the ignition and operating system are footnoted to the archived manual rather than to the product page, and the defect in HK's magazine-weight column. Only what is specific to the .45 is repeated here. THIS IS THE CALIBER ROW THAT PROVES THE PAGE'S THREE CHAMBERINGS ARE THREE RECORDS. HK's dimension table gives 9 mm x 19, .45 AUTO and .40 S&W their own rows, and the .45 differs on every axis but width: 201 mm long against the 9 mm's 195 mm, 142.5 mm tall against 135 mm, a 112 mm barrel against 108 mm, 887 g against 770 g, and a 161 mm sight radius against 158 mm. Only the 32 mm width is shared. A record built by reading the first row of that table would have been wrong on four measurements while looking entirely well-formed — the CZ Shadow 2 failure shape, arriving here as a table row rather than an embedded product. Capacity and trigger action follow the SKU as on the 9 mm: the spec row reads "10/12 Rounds" and "SA/DA, DAO" without designating either, and catalogue number 81000322 is the V1 double-action/single-action configuration shipping two 12-round magazines. The V7 LEM configurations, the night-sight configurations and the USP45 Tactical are separate listings. Trigger pull is HK's 20 N (SA) and 51 N (DA), published in newtons for every caliber alike, with both pound figures converted by this directory and flagged. Every published unit pair on this row was checked and reconciles, including the weight exactly — 887 g is 31.29 oz and HK prints 31.29. Frame class is unset and year introduced is unrecorded, as on the 9 mm. Also published and unrecorded for want of a schema field: a 161 mm / 6.34 in sight radius, a polygonal bore profile, a fibre-reinforced polymer frame, a patented recoil reduction system, a Lock-Out safety device, and the $1,149 MSRP.

MSRPNot recorded
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 Heckler & Koch USP45 (V1)?

The Heckler & Koch USP45 (V1) is chambered in .45 ACP. Heckler & Koch writes it as .45 AUTO. Ammunition should match the exact chambering marked on the firearm.

02How many rounds does the Heckler & Koch USP45 (V1) hold?

Heckler & Koch lists a 12-round standard magazine for the USP45 (V1). Heckler & Koch also lists 10-round capacity as optional. These are magazine capacities; a round carried in the chamber is not counted here.

04What are the dimensions of the Heckler & Koch USP45 (V1)?

Heckler & Koch publishes 201 × 32 × 142.5 mm / 7.91 × 1.26 × 5.61 in. Any measurement basis shown is the manufacturer's own qualifier; where none is shown, the manufacturer states none.

06Is the Heckler & Koch USP45 (V1) striker-fired?

07What is the trigger pull on the Heckler & Koch USP45 (V1)?

Heckler & Koch lists 51 N / ≈11.47 lb (double-action); 20 N / ≈4.5 lb (single-action). A published figure is a specification rather than a measurement of any individual firearm.

08Does the Heckler & Koch USP45 (V1) have a warranty?

Heckler & Koch states: Lifetime Limited Warranty on all new Heckler & Koch Inc. firearms purchased after January 1, 1998, to the original retail purchaser only and for that purchaser's lifetime — extendable to a donee named at the time of the original purchase, valid only on firearms imported into the United States and distributed by HK Inc., and applying only to retail purchases by individuals through an authorized HK dealer. Two exclusions are stated: firearms bought by United States military, government, law-enforcement or security organizations for duty issue instead carry a one-year limited warranty, or whatever a valid contract specifies; and rimfire .22LR rifles and pistols carry a one-year warranty. Terms are as published at the date this record was checked and may vary by region.

Source conflictThis record’s sources disagree, and it is on the register: A 9 mm magazine listed at the weight of the pistol · A manual whose dimension column does not convert. Nothing was repaired to resolve it — see the entry for what the sources publish and what this record does with it.
