Since my P99 has been "upgraded" to CCW use, I am putting the stock guide rod back in and am selling this. It is a Springco polished stanless steel dual spring recoil reducer and guide rod for the 9mm P99 full size. Works great, and really does reduce recoil. Great for having new shooters get used to the 9mm. Cost over $80, but will sell for $50 shipped via paypal. Email if interested to [email protected] Thanks.
