  • Aluminium construction
  • Ambidextrous functionality
  • For TM EU17 Gen.4 and EU19 GBB pistols

Adding a cocking handle to your pistol might seem a bit much, but in the modern-day and age of primary pistols becoming more and more popular the pistol needs to give up some of its concealment characteristics to become more than "just" a sidearm and compete in the modern CQB site. The Tactical Cocking Handle from CowCow is an ideal solution, providing a protrusion on either side of the slide to allow the pistol to be cocked more quickly and easily, even allowing for one finger cocking from either side! This cocking lever adds a whole lot of functionality but is more compact than competition optimised designs, allowing it to still be used with most tactical holsters whilst reducing snags. This cocking lever replaces the back plate of the slide on your TM EU series pistol.
