Designed for heavy duty use, SIGMECH Tungsten Heavy Alloy (WHA) guide rods are over-engineered to perform and exceed expected mechanical use. Each SIGMECH WHA guide rod is precision ground to tight tolerances using specially selected US sourced, high-grade tungsten that is then finished with a high-polish, low-friction surface for extremely smooth cycling and excellent wear resistance that lasts longer and performs better than standard steel guide rods.

Overall, these guide rods are engineered for operators looking to squeeze every last ounce of performance from their P320 by providing robust impact resistance and introducing 2.30oz (2.60oz assembled weight) of leverage to the front-end of the slide, effectively reducing muzzle flip and felt recoil. The 1911 style rod also makes it easier to fine tune P320 performance to operator preference by using standard 1911 and ISMI 1911 tuning springs.

Each SIGMECH Tungsten Heavy Alloy guide rod also comes with a Limited Lifetime Warranty!

Note: Requires a 1911 style spring (sold separately)
