Looking for the ultimate upgrade for your Sig P365? The Radian Ramjet + Afterburner Combo is purpose-built to deliver real performance where it matters — accuracy, control, and concealability. Whether you're enhancing your EDC or tuning a carry pistol for duty or defense, this combo packs a serious punch.
Crafted from 416R stainless steel, the Ramjet barrel is precision-machined for match-grade accuracy, while the Afterburner compensator uses Radian’s INTRA-LOK® system for secure, tool-free installation. The threadless design eliminates timing issues and allows quick removal for cleaning.
