Based on
Manufacturer documented

Based on manufacturer documentation or support information.

Requires a THREADED BARREL in 1/2-28 or M13.5x1 LH. Most of these pistols do not ship with one — check your barrel before buying. Compatibility (read 2026-09-21): "Full size P320's, P320 X Compact, P320 Compact, P320 X Carry (with 1/2-28 or M13.5x1 LH threaded barrels)." Same four configs as the HC320. The flush-fit paragraph recommends this body for a 3.6" slide on a full-size frame; that is a build recipe. Not compatible with Bar-Sto, KKM, or EFK. Legion is a spring caveat.

Check your exact model and part before ordering. Fitment limits
