SEE THE hk-usp9 RECORD for the shared reasoning: the Web Archive sourcing and why hk-usa.com cannot be fetched directly, why heckler-koch.com cannot substitute, why the ignition and operating system are footnoted to the archived manual, and the defect in HK's magazine-weight column. THIS RECORD'S DIMENSIONS ARE IDENTICAL TO THE 9 MM'S AND THAT IS NOT A TRANSCRIPTION ERROR — the note exists so nobody 'corrects' it. HK publishes 195 mm overall length, 135 mm height, 32 mm width, a 108 mm barrel and a 158 mm sight radius for both the 9 mm x 19 and .40 S&W rows, which is what a shared frame and slide produce. The two records differ where the caliber actually changes things: weight, 820 g against the 9 mm's 770 g, and magazine capacity, 13 against 15. Contrast the .45 row, which differs on every axis but width. **The reason to record all three separately is not that their numbers always differ, it is that HK publishes them as separate rows and the base-model rule follows the maker's own divisions** — the fact that two rows agree is a finding, not a licence to merge them. Capacity and trigger action follow the SKU as on the other two: the spec row reads "10/13 Rounds" and "SA/DA, DAO" without designating either, and 81000314 is the V1 double-action/single-action configuration shipping two 13-round magazines. The V7 LEM configurations and the night-sight configurations are separate listings. Trigger pull is HK's 20 N (SA) and 51 N (DA), the same figures it publishes for every caliber, with both pound values converted by this directory and flagged. Every published unit pair was checked and reconciles within rounding; the weight is the loosest at 820 g against a printed 28.96 oz where the arithmetic gives 28.92, which is last-digit noise rather than the ounce-sized gap found on the VP9. Chambering needs no published-wording field: HK's spec row prints ".40 S&W", which is already the directory's own spelling, so `manufacturerChambering` stays unset rather than reporting agreement as a gap. Note HK's SKU description writes the same cartridge as ".40cal", a third spelling that is not recorded because the specification row governs. Frame class is unset and year introduced is unrecorded, as on the other two. Also published and unrecorded for want of a schema field: a 158 mm / 6.22 in sight radius, a polygonal bore profile, a fibre-reinforced polymer frame, a patented recoil reduction system, a Lock-Out safety device, and the $1,119 MSRP.

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 USP40 (V1)?

The Heckler & Koch USP40 (V1) is chambered in .40 S&W. Ammunition should match the exact chambering marked on the firearm.

02How many rounds does the Heckler & Koch USP40 (V1) hold?

Heckler & Koch lists a 13-round standard magazine for the USP40 (V1). Heckler & Koch 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 Heckler & Koch USP40 (V1)?

Heckler & Koch lists a barrel length of 108 mm / 4.25 in.

04What are the dimensions of the Heckler & Koch USP40 (V1)?

Heckler & Koch publishes 195 × 32 × 135 mm / 7.68 × 1.26 × 5.31 in. Any measurement basis shown is the manufacturer's own qualifier; where none is shown, the manufacturer states none.

05How much does the Heckler & Koch USP40 (V1) weigh?

Heckler & Koch publishes 820 g / 28.96 oz (HK's own column heading).

06Is the Heckler & Koch USP40 (V1) striker-fired?

Hammer-fired. Heckler & Koch publishes this as "SA/DA". This is recorded from the manufacturer's own classification rather than inferred from the mechanism.

07What is the trigger pull on the Heckler & Koch USP40 (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 USP40 (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.
