Our kit provides an ultra-clean break that is tuned to suit your particular pistol and needs, while preserving the outstanding mechanical drop-safety qualities.

The kit is specifically designed for guns that have gone through SIG Sauer’s Voluntary Upgrade Program.

All of our work can be completed on any P320 variant, including the X-Five.

You can purchase the Competition Kit - Hybrid or Straight - without installation services and have it locally installed by any qualified gunsmith in a SIG factory-upgraded P320.
