Finish or upgrade your factory or 80%-built P320 platform with a quality barrel.
Shooters love the P320 platform because of its modularity: Grips, barrels, slides, even calibers can be swapped out in a matter of minutes. Whether you're fabricating a MUP-1 80% insert or just swapping out the configuration on your factory handgun, you'll find a quality P320 barrel right here at the right price.
Every Sig P320 barrel we sell is precision-forged from 4150 CMV, arguably the hardest and toughest gun barrel steel on the market. Each barrel's also treated with QPQ Nitride, providing a high-temperature protective finish that withstands extreme heat and corrosion. Each barrel also sports match-grade rifling that's been heat-treated to obtain a high hardness rating, perfect for withstanding rapid fire and repeat mag dumps.
