(5 out of 5) What an AMAZING deal on a FN 509!
by Marion from Scottsdale, AZ on October 6, 2023

Not sure how this flew under the radar for some. Not going to say much about the pistol because you probably already know that it's top class. But what about the price!! So...to start the $929 is a solid price on its own and close to what you can find if you spend time searching the web for hours. BUT ADD ON the FN $100 rebate. BUT THEN ADD ON the $130 store gift card. BUT THEN ADD ON the 2 free 24 rd mags $140 value. Now you can see exactly how amazing this deal is! Thank you Sportsmans Outdoor....I am a fan for life!
