The 9mm Ronin Operator followed the 45 ACP version after market feedback made clear that the two-tone aesthetic and forged construction were compelling at the Ronin price point regardless of caliber. The 9mm version runs lighter recoil springs and a slightly different extractor geometry tuned for 9mm pressures, but shares every cosmetic and structural element with the original. It is the more practical range and defensive choice for the majority of buyers.
