Sig Sauer Caliber X-Change Kit, 9MM, (1)-17 Round & (2)-21 Round Magazines, 4.7″ Configuration

Product Description

The Sig Sauer Caliber X-Change Kit is a 9mm conversion kit in the 4.7 inch configuration, built around a 17-round capacity. It is sold as a kit with one 17-round magazine and two 21-round magazines, so you start with three magazines in two sizes.

The point of an X-Change kit is simple. It lets you change the caliber setup of a compatible Sig Sauer pistol without buying a whole new gun. This one is set up for 9mm, which is a common choice for range days, training and carry practice.

Who it suits

This kit suits a Sig Sauer owner who wants a 9mm setup in the 4.7 inch configuration. The mix of 17-round and 21-round magazines gives you a standard-size option and a higher-capacity option. That helps for drills, classes and long range sessions where you do not want to stop and reload often.

Check that the kit fits your pistol before you order. If you are not sure, match the manufacturer part number, 8900267, against what your gun needs.

For gear, think about what a 9mm shooter already uses. A holster that fits your pistol, magazine pouches, a range bag, eye and ear protection, and a cleaning kit all pair well. You will also need 9mm ammunition for practice and for carry.
