The Sig Sauer P365X Macro pistol in 9mm with 17-round capacity (brand part no. 365XCA9BXR3) is the highest-capacity model in the P365 family, pairing a Macro Compact grip module with an X-Series optic-ready slide. Sig Sauer builds the pistol with a 3.7-inch barrel, a Nitron finish, and night sights, and interchangeable backstraps let shooters dial in the grip. The optics-ready X-Series slide is compatible with the SIG ROMEO Zero Elite, and a 1913 rail supports lights and lasers. Two 17-round steel magazines ship with the pistol at 22 ounces unloaded.
