Rebuilding Gun Trader: A Faster Platform for the UK's Biggest Gun Marketplace

Gun Trader has been the UK's main marketplace for buying and selling firearms, optics and shooting equipment for years, built up around a large, loyal community of dealers and private sellers. The platform it ran on had not kept pace with that growth. We rebuilt the eCommerce side of the site from the ground up, focused on speed, search and a checkout that does not lose people halfway through.

The brief was not a redesign for its own sake. Gun Trader's listings are dense: calibre, action type, barrel length, licence requirements, dealer location, all fields serious buyers actually filter by. Our job was to keep that depth while making the site feel fast and modern rather than like a spreadsheet with photos. We rebuilt the listing and search architecture so filtering across thousands of live listings stays instant, restructured product pages around the details a buyer checks first, and cleaned up the path from a listing to a completed sale for both dealers and private sellers.

Performance work made up a large share of the project. A marketplace this size lives or dies on how quickly a search result loads and how reliably a listing renders on a slow connection at a country gun show with patchy signal, not just on a fast office broadband line. We treated page weight and load time as product requirements from the start rather than an afterthought to fix after launch.

Working in a regulated category like firearms sales adds a layer most eCommerce rebuilds do not have to think about: licensing information, age verification prompts and dealer credentials all need to be visible and trustworthy without turning every page into a wall of compliance text. Getting that balance right, useful and reassuring rather than bureaucratic, mattered as much as the performance numbers.

The result is a platform built for how Gun Trader's users actually shop: fast search, clear listings, and a checkout that gets out of the way. It is the kind of rebuild that will not win a visual design award, and was never meant to, but it is the sort of unglamorous, high traffic eCommerce work that makes up a good share of what we do at ZKO alongside the 3D and motion projects.
