About MatchMyGun
We built the world's largest firearm and ammunition compatibility database because finding the right ammo for your gun shouldn't require three browser tabs, a reloading manual, and a forum post from 2009.
Our Mission
MatchMyGun exists to provide accurate, verified, and comprehensive firearm data in one place — free of marketing fluff, forum hearsay, and outdated information. Every caliber spec is sourced from manufacturer data. Every guide is researched and cross-referenced against published ballistics data. Every comparison table includes real numbers, not opinions.
We don't sell guns. We don't take affiliate commissions from retailers. Our incentives are aligned with accuracy — because our reputation depends on it.
