Overview

The P320 Compact occupies the sweet spot between concealment and capability. With a 3.9-inch barrel and compact grip module, it's sized similarly to the Glock 19 - small enough for concealed carry but large enough for comfortable range sessions and home defense. The compact uses the same modular FCU as all P320 variants, maintaining full parts interchangeability.

The reduced grip length accepts 15-round magazines standard, with full compatibility to extended magazines when concealment isn't required. The shorter slide and barrel reduce weight to under 26 ounces, making it comfortable for all-day carry. Despite the smaller size, the Compact retains the full-length accessory rail for weapon lights and lasers.

This is the P320 variant most comparable to the M18 military sidearm, offering proven military-grade reliability in a package optimized for everyday carry. The Compact represents the best balance of the P320 line - capable enough for duty use, compact enough for concealment, and modular enough to adapt to any role.
