SIG SAUER P320 9mm Spectre COMP Complete Barrel Assembly by Bob, Verified Owner, June 20, 2025
Works and fits great on the P320 5X Legion, right out of the box. Runs factory 115 and 125 grain all day, zero stove pipes or failures in 700 rounds. I highly recommend it. I'm very pleased.

good product but used by rg, Verified Owner, August 16, 2024
