This Hinderer copper pen was designed and manufactured using state of the art CNC and CAD_CAM technology. Properly placed traction grooves give a good firm grip when using pen in a CQB mode. Course threads used throughout for extra thread height which translates into a very strong tough thread able to take the punishment of hard strikes.
Modular design so the user may add a multitude of 17-4 Stainless Steel end attachments to configure the pen however the person or mission dictates.
