Sig Sauer P320-M18 California-Model 9mm Compact (LCI Missing; Not CA-Compliant as Configured), Manual Safety, Coyote PVD, Front Night Sight Only (rear sight/plate missing), 3.9 in Barrel, 3x 10-Round Mags, Streamlight TLR-8
This Sig Sauer P320-M18 is the California-model, manual-safety variant of the compact 9mm platform, finished in coyote-tan PVD and equipped with a front night sight; the rear sight/optics cover plate is missing. It was manufactured as MPN 320CA-9-M18-MS-CA with the CA-specific slide; however, the top-mounted loaded chamber indicator (LCI) assembly is currently absent, so as configured it is not California roster compliant. It includes three 10-round steel magazines marked Made in Italy, the factory case with matching serial label, and a Streamlight TLR-8 light/laser installed. The modular stainless-steel FCU and carry-length coyote grip module round out a feature set designed for duty-ready practicality.
Condition
Overall Condition: Good condition, showing some signs of prior use and handling.
Bore Condition: Excellent - Clean, mirror finish, no signs of wear.
Bore Rifling: Excellent Rifling - Sharp lands and grooves.
Specific Condition Notes: Minimal handling marks are present. The optic cut cover plate is not included. As a result, the rear sight (integral to that plate) is not installed. The chamber indicator and spring are not included.
What’s Included
- SIG Sauer factory hard case with matching serial label
- Owner's manual
- 3x 10-round steel magazines (marked Made in Italy)
- Streamlight TLR-8 light/red laser combo (installed)
- Adhesive grip tape wrap installed on grip module
The P320-M18 California model was added to the roster on Aug 31, 2023, pairing the M18 feature set with a 10+1 capacity and ambidextrous manual safety. This example was manufactured as that model but is not California compliant as configured due to the missing LCI assembly. It is built around Sig Sauer's modular, serialized stainless-steel FCU for easy configuration within the P320 ecosystem.
The compact slide features front and rear serrations and a durable coyote-tan PVD finish over stainless steel. The carry-length coyote polymer grip module provides a consistent, duty-focused profile, and the integral M1913 accessory rail on the dust cover supports mounted lights and lasers.
Front night sight provides a clear low-light aiming reference; the rear sight/plate is not installed. Dimensions are compact and balanced with a 3.9 in barrel, 7.2 in overall length, 5.5 in height, and 1.6 in width, at a weight of 28.1 oz.
This example includes useful additions: a Streamlight TLR-8 light/red laser installed for immediate illumination and aiming capability, plus an adhesive grip tape wrap for added purchase. Three steel magazines marked Made in Italy are included, and the case label matches the pistol's serial number for straightforward provenance.
