I recently noticed a trigger kit made by patriot that claimed to reduce the trigger pull on the walther ppk/s . it claimed to reduce the pull on the double action while keeping it smother than orginal . It states to reduce it by 37% which equates to 12 pounds. It states it is easy to do . I would love to buy it but was skeptical it was selling on ebay for 12.00 . Has anyone heard or used this .
