DPM Mechanical Recoil Reduction System | Stealth Arms Platypus 4.25" (Stainless)

Overview: Upgrade your Stealth Arms Platypus 4.25" with the DPM Mechanical Recoil Reduction Rod — a direct replacement for the factory recoil rod that reduces felt recoil, protects slide & frame, and improves follow-up speed without changing pistol configuration. This version is offered in stainless steel (no black-oxide coating).

Key Features
