Glock 47 vs. Glock 17

Four dimensions, four exact matches.

Most comparisons on this site begin with a difference. This one begins with its absence: Glock lists the G47 and the G17 Gen6 at the same overall length, the same width, the same height on the same stated basis, and the same barrel length. Not close — the same numbers, in both unit systems. The listed trigger pull matches at 26 N, and the standard magazine matches at 17 rounds.

That is why this page carries no dimensional overlay and no capacity plate. Every other comparison brief in this directory draws those because the figures diverge; drawing them here would render one outline twice and imply a difference the sources do not contain. A blank where a chart would be is the honest rendering of two identical spec rows.

Three things do separate the records, and each is a different kind of difference: a measured one, a labelling one, and a catalogue one.

Identical outside, 58 grams apart.

The G47 is listed at 658 g without a magazine against the G17 Gen6’s 600 g, and at 735 g against 680 g with an empty magazine. That is 2.05 oz and 1.94 oz respectively — consistent with each other, as they should be, since the difference between the two bases is just the magazine.

Both deltas are publishable, and that is worth pausing on, because most of this section is taken up with weights that cannot be subtracted. Here one manufacturer publishes both figures for both pistols and names the basis for each. Same maker, same convention, same rows: nothing has to be assumed to reach the gap.

What Glock does not publish is why. Two pistols with identical published external dimensions do not have identical masses, and no cited page accounts for the difference. This directory records the gap and declines to explain it, which is the same discipline that keeps a spec row blank rather than filled with a plausible guess.

One of these pistols has a generation. The other does not.

The G17 record here is the Gen6, and Glock says so everywhere: the product page, the heading, and a dated January 2026 launch release. The G47 record carries no generation at all, and that is a transcription, not an omission. Glock’s page and the model’s owner’s manual both read simply “G47.” A “Gen 5 MOS” label that once described this pistol in an earlier scope of this directory was not carried forward, because Glock does not print it.

This matters more than a naming quibble, because it puts the two spec sheets on opposite sides of a generation boundary while their numbers agree exactly. The G47’s figures belong to a pistol Glock released commercially in 2023; the G17’s belong to a model line Glock launched in January 2026 with a flat-faced trigger, a palm swell and thumb rest, and an integrated optic-ready system. Two matching dimension tables across that gap are a fact about the tables, not a statement that the pistols are the same design.

The parts-compatibility question follows from the same place. Glock states compatibility with the G17, G19 and G45 Gen5 MOS models — not with the Gen6 G17 recorded here. That is a claim about a different set of pistols than the one on this page, and it is left as Glock stated it rather than extended to the record that happens to share a table.

MOS is not a variant of the G47. It is the G47.

This directory’s base-model rule normally files an MOS pistol as a variant of a non-MOS listing. The G47 has no such listing: Glock catalogues it in MOS configuration only, so the MOS pistol is the base record here, recorded as such by decision in August 2026. The Gen6 G17 arrives at the same optic-ready end by the opposite route — Gen6 pistols ship optic-ready as standard, so there is no separate Gen6 MOS variant to compare against.

The catalogue split is the other asymmetry. The G17 Gen6 sits under commercial firearms; the G47 sits under law enforcement. Glock states the model was developed for US Customs and Border Protection in 2019 and released commercially in 2023, and the year introduced on the record follows the commercial release rather than the development date.

The optional-capacity row runs the same way. The G47 lists 17-, 19-, 24-, 31- and 33-round options; the Gen6 G17 lists none at all. The Gen5 G17 page did list optional figures, which is why a capacity claim carried over from a Gen5 comparison has no current source behind it — the same trap the Glock 19 vs 17 brief documents on the other model.

What the data supports—and what it cannot.

The two listings settle dimensions, barrel length, trigger pull, capacity, optional capacities, optic arrangement, catalogue placement, launch year and warranty. They do not settle why the masses differ, whether any part of one fits the other, or which pistol suits any particular lawful use. On a pair this closely matched, the temptation is to reach for a difference that sounds decisive; the sources support exactly one, and it weighs 58 grams.
