Frequently Asked Questions

What are the key differences between the Sig Sauer M18 and M17 pistols?

What is included in the Sig Sauer M18 pistol package?

The Sig Sauer M18 typically comes in a hard case containing the pistol, one 17-round standard magazine, two 21-round extended magazines, an owner's manual, and a cable lock, ready for immediate use or training.

What safety improvements does the Sig Sauer M18 offer over earlier P320 models?

The M18 incorporates an updated trigger mechanism with a reduced mass, specifically designed to prevent accidental discharges if the pistol is dropped. This addresses concerns raised by early P320 models.

Is the Sig Sauer M18 suitable for concealed carry?

While the M18 shares the full-size grip of the M17, its shorter 3.9-inch barrel and slide make it more manageable for concealed carry compared to the M17, though holster selection and personal comfort are key factors.
