Help CenterAll of our current SIG P320C and P320 Full Size offerings are compatible with the SIG M18 & M17 pistol models.
Customers looking for a holster for their M18 should select the P320C option in our builders, and customers looking for a holster for their M17 should select the P320 Full Size option. Some customers may have both the M18 and M17 - in this instance, the P320 Full Size option will work for both models.
