Sig Sauer Caliber X-Change Kit, 9MM, (1)-17 Round & (2)-21 Round Magazines, 3.9″ Configuration

Product Description

The Sig Sauer Caliber X-Change Kit P320-M18 is a 9mm conversion kit with a 3.9″ configuration and 21-round capacity. It changes a P320 into the non-manual safety version of the M18. The finish is Coyote, so the pistol picks up a tan look.

What is different about this kit

The key difference is the safety setup. This kit gives a P320 the non-manual safety version of the M18, so there is no manual safety lever to work. If you prefer a pistol that runs without one, that is the point of this configuration. The 3.9″ configuration and the 9mm chambering round out the package.

It is built for people who already own a P320 and want the M18 setup without buying a whole new pistol. It also suits shooters who like the P320 platform and want a Coyote-finish option. The manufacturer part number is 8900268, which helps when you are matching parts or checking records.

Gear that pairs well is simple. Look at a holster made for the P320 M18 configuration and confirm the fit before you commit. Add spare 9mm magazines, a quality supply of 9mm range ammunition, a cleaning kit, and a padded range bag. A good pair of eye and ear protection rounds out a day at the range.
