Dayton Gun & Knife Show 2026 in Dayton, Ohio

The Dayton Gun & Knife Show takes over the Montgomery County Event Center in Dayton, Ohio on October 17–18, 2026. Over two days, licensed dealers and private collectors fill the hall with antique pistols, hunting rifles, modern sporting arms, combat knives, swords and a broad selection of edged tools. The floor also covers cartridges, coins, militaria, holsters, gun safes, cases, fishing tackle and outdoor survival gear. Because both trade sellers and individual collectors set up tables, the show is a solid stop for trades, appraisals and hard-to-source pieces. It is promoted by C & E Gun Shows, Inc., a family-run operator that has been running gun shows across the Midwest and Mid-Atlantic since 1986. The event is open to trade buyers and the general public, with tickets sold online through the promoter's ticketing partner. Visitors coming from out of town can stay near the Infirmary Road venue, a short drive from the show floor and the rest of Dayton.
