Primary Arms vs RSR

Both catalogs are synced into one shared vocabulary, so the same UPC can be counted on either side and matched across them. Everything below is what we measured in the two feeds — how much each one lists, how much of it is the same product, and what only one of them carries.

What each one lists most of

Primary Arms and RSR describe their catalogs in their own words, and we resolve both against one shared product vocabulary before counting. A category below therefore means the same thing on either side. Each list is that distributor’s own largest categories, counted in active listings.

Parts & Components, Optic, Ammunition and Magazine appear in both lists, so those counts can be read against each other directly.

Each list stops at that distributor’s eight largest categories. A category on one list and not the other is one we have not counted here, not one that distributor does not carry.

Where each one will ship it

Taken from each company’s own site on the dates shown on their individual pages. Running a drop-ship programme and naming where the parcel goes are separate questions, and most distributors answer only the first — so “Not stated” below means they have not published it, not that they refuse.

RSR says they drop-ship but does not publish where the parcel goes. Ask them before you promise a customer a delivery address.

Every distributor here ships to your own licensed premises — that is what a wholesale account is, not a policy any one of them publishes. Confirm anything you will act on directly with the distributor.

Which should you open?

RSR lists 29,797 distinct UPCs to Primary Arms's 811 — about 36.7× the breadth. 486 UPCs are carried by both — 60% of what Primary Arms lists and 2% of what RSR lists. Beyond that overlap, 325 UPCs appear on Primary Arms alone and 29,311 on RSR alone. If you open one account, RSR is the wider of the two on its own — it leaves 325 UPCs unreachable, against 29,311 if you open Primary Arms instead. Carrying both reaches 30,122 distinct UPCs, 325 more than RSR covers alone. The largest category in both lists is Parts & Components — RSR lists 6,481 there to Primary Arms's 216. Both feeds answered us 99.9% of the time over the window we monitor.

This is arithmetic on the counts above, not a recommendation of one company over the other. Which account is worth opening also depends on terms and on what your customers ask for, neither of which is in the catalog data we measure. What each company publishes about shipping destinations is in the table above it.

Primary Arms

Primary Arms syncs the smallest catalog Project Parabellum connects to today, delivered through a dealer API on the same automated schedule as the other API-connected distributors here. Because the catalog is narrow, it works best as a secondary source that fills a specific gap rather than as the account a storefront builds its general inventory around.

RSR

RSR Group syncs a broad catalog spanning handguns, long guns, ammunition, optics, and a deep accessory line through a dealer API. Project Parabellum pulls RSR's full catalog and stock positions on the same automated schedule as the other API-connected distributors, so a dealer can see what RSR has today rather than relying on a static, periodically-updated catalog file.

Applying for a dealer account

Both links leave this site. Applications are submitted to, reviewed by, and approved by the distributor themselves — Project Parabellum is not part of that process and cannot speed it up or vouch for you.

Project Parabellum is not affiliated with Primary Arms or RSR, and neither distributor reviews or supplies this page.

The counts here are our own measurements of the feeds we sync, refreshed hourly. They describe what each distributor sends us, which is not the same thing as everything either company sells, and they will differ from figures published elsewhere.
