HK VP9 vs. VP9-B

One control, and HK spells it out.

The B is a push-button magazine release, fitted in place of the VP9’s ambidextrous paddle lever. That is not an inference from the letter: HK groups the SKUs under the catalogue heading “VP9 Push Button Magazine Release,” which is the maker explaining its own model code. Where a maker does not explain one — Springfield’s “GU23,” the Echelon’s “4.5F” — this directory leaves the suffix unexpanded rather than guess. Here it did not have to.

Everything else HK publishes for both pistols matches exactly: 186.5 mm overall, 137.5 mm tall, a 104 mm barrel, a 162 mm sight radius, a 24 N trigger with 6 mm of travel and a 3 mm reset, the same weight, and the same 17-round standard magazine with 10 and 15 also listed. The two records differ in their catalogue numbers — 81000283 and 81000285 — and in nothing measurable.

Which makes the two blanks on the VP9-B record the whole story, and neither is an oversight in this directory.

HK publishes a width for the VP9. It does not publish one for the VP9-B.

The VP9-B’s dimension table is headed “Caliber | Length | Height | Barrel Length | Sight Radius.” The VP9’s, on an otherwise identically formatted page one click away, carries a width column reading 33.5 mm / 1.32 in. HK simply omits it on the B.

The temptation to carry the figure across is stronger here than anywhere else in this directory, and the reason is that the inference looks unarguable. These two pistols differ in their magazine release. A magazine release cannot alter the width of a slide. The number is on HK’s own site, for HK’s own pistol, under a heading HK wrote.

It was still not carried across, and the principle is worth stating exactly: “obviously the same” is not a citation. Every figure on this site answers the question “which document says so, and when was it read?” A transplanted width has no answer — the document that says 33.5 mm says it about a different catalogue number. Once a value can be moved between records because moving it seems safe, the per-value sourcing that makes the rest of the table worth quoting stops meaning anything.

So the VP9-B’s width row reads as not published, and the dimensions row names the missing axis rather than presenting four figures as a complete set. Readers who want the number can have it with its actual provenance: HK publishes 33.5 mm for the VP9, and does not publish a width for the VP9-B.

Both pages give the same weight twice, and the two figures do not match.

HK publishes 753 g and 25.56 oz under a row headed “Weight (with empty magazine),” on both pistols. But 753 g is 26.56 oz, and 25.56 oz is about 724 g. The two figures HK gives for one pistol are a full ounce apart, and the digits differ by one, which looks like a transcription slip in the imperial value.

Both stand as published on both records, and neither is flagged as converted. Flagging one would credit this directory with arithmetic it did not do; picking the “right” one would be a repair rather than a record. Every other pair on both pages reconciles cleanly — 186.5 mm against 7.34 in, 137.5 mm against 5.41 in, 104 mm against 4.09 in, 24 N against 5.4 lb — so the discrepancy is confined to one row, and it is confined to the same row on both pistols.

The measurement basis, at least, needs no inference for once: HK heads the row itself. That is the field that most often has to be guessed at elsewhere in this directory, and here the maker names it.

The VP9 has a launch year. The B did not inherit it.

HK’s press release, datelined June 10, 2014, announces “its new striker fired VP9 pistol.” It announces the VP9, not the variant, and no VP9-B announcement exists anywhere in the archive — a targeted query returned only the product page, its media gallery and two oEmbed endpoints. So the VP9 record carries 2014 and the VP9-B record carries no year at all.

Dating the B from its parent’s release would be the same borrowing as copying its width: a document about one catalogue number, applied to another because the two are obviously related. The blank is the accurate rendering.

Both records are built from archived captures, and that is disclosed rather than hidden.

hk-usa.com serves a Cloudflare challenge to every request, including its robots.txt, and this project does not attempt to defeat bot protection. Both records are therefore built from Web Archive captures of HK’s own manufacturer-authored pages: the VP9 as captured February 16, 2025, the VP9-B as captured December 2, 2024. Each capture was content-checked before use, because an archived URL can preserve a challenge page and return HTTP 200 like anything else.

Both are live products, so both records are as-published at their capture dates and could have drifted since. The two captures are also fourteen months apart from each other, which is worth knowing before treating the matching figures above as proof that HK has never changed either page.

HK’s international site is served without a challenge and publishes a full specification block, and it was deliberately not used. HK sells this pistol in Europe under a different model name, and the string “VP9” does not appear anywhere in that site’s sitemap. Recording figures from a differently-named product would be an identity claim made by this directory rather than by HK — the same refusal as the width, arrived at from the other direction.

What the data supports—and what it cannot.

The two listings settle the control difference, every shared dimension, capacity, trigger figures, ignition, warranty and the VP9’s launch year. They do not settle the VP9-B’s width, its launch year, the trigger mode of either pistol — HK says only that the trigger has a “single action type break,” which describes a feel and not a classification — or the operating system, since a modified Browning system names how the barrel locks rather than how the pistol cycles.

And they do not settle whether a paddle release or a button suits any particular person or use. That is the actual question behind most searches for this pair, and it is one no specification table answers.
