About this pistol barrel
Rival Arms Steel Drop in Barrel for SIG P320 Full Size 1:10 Twist Black is a pistol barrel for Sig Sauer, 3.90 in, 1:10 in twist.
Match the pistol model, generation and slide length exactly; a barrel one generation off will not lock up correctly. Drop-in barrels fit most factory slides, while match-grade barrels may need a gunsmith to fit the hood and lug.
