Killer Innovations Precision Machining with Single Process Technology

Manufactured from superior 416R steel, the Velocity SIG P320C barrel is precision machined with the Killer Innovations developed Single Process Technology (S.P.T). S.P.T. means that the chamber, bore, and rifling is all machined with one high-tech precision machine without any human interference. The barrel rifling is cut with the meticulous Single Point Cutting technique that makes 120 near-exact cuts that promise only the absolute top-of-the-line quality in your Velocity SIG P320C barrel.

Outstanding Tolerances Will Improve Your Performance

Your performance can only improve with the combined outstanding dual technologies of Single Process and Single Cut technologies that Killer Innovations have harnessed. Button barrels and standard cut rifling techniques simply cannot produce the consistent accuracy and razor tolerances that Killer Innovations always provides. This all translates into better consistency, superior accuracy, and more of your rounds down range and on target. For your next upgrade, choose the Velocity barrel for the SIG P320C and bring your pistol to the next level.
