Overview

This Caliber X-Change kit is designed to convert a compatible P320 into a TACOPS-style 9mm setup using your existing 9mm, .40 S&W, or .357 SIG fire control module. It includes a complete slide assembly with suppressor-height night sights, a threaded barrel with thread protector, a recoil spring, a carry grip module, and one 21-round 9mm magazine. The configuration is suited to shooters who want a ready-to-assemble carry-oriented package with suppressor-capable features already included. It is not compatible with .45 ACP fire control units, so fitment should be checked before purchase.

Considerations & Trade-offs

  • The kit is not compatible with .45ACP fire control units, so it is limited to the specified P320 configurations.
  • It is intended to upgrade an existing P320 using a current fire control module, rather than serving as a complete standalone pistol.
  • The package is centered on a TACOPS-style setup with a threaded barrel and suppressor-height night sights, which may be unnecessary if those features are not part of your intended use.
  • The included 21-round magazine and carry grip module are specific to the kit’s configuration, so compatibility and fit should be confirmed against your existing setup.
