The Compact PRO configuration pairs a striker-fired action with a flat-faced trigger and no manual safety. The black polymer grip module features a molded SIG medallion, while the stainless-steel barrel and serialized stainless-steel FCU provide a durable core.
The Pro-Cut slide is optics-cut to SIG's R2 footprint and ships with a cover plate. It is compatible with SIG ROMEO1PRO and Leupold DeltaPoint Pro footprints when the plate is removed. The rear sight is dovetailed into the cover plate, and the front sight is a green-dot tritium post marked TG-H3 for low-light visibility.
SIG's modular FCU design enables straightforward caliber and size swaps within the P320 family. This compact model uses 15-round steel magazines (marked "MADE IN ITALY") for a 15+1 capacity and includes a frame accessory rail for mounting lights or other compatible accessories.
Documentation includes a factory case label dated 01-APR-2020 that matches the pistol's serial and confirms the exact model/SKU L320C-9-BXR3-PRO. Country of origin is the USA.
