The Taurus PT 809 pistol is a polymer handgun that offers a lot of value for a modest price. The pistol was chambered in 9mm and would anchor a line that included models chambered for the .40 S&W and .45 ACP as well as compact variants.
Taurus discontinued the 809 pistol some years ago, so my guess is you either have one or are looking to purchase one from a buddy. So, let me go over the history of the gun and give you my take on it. Some aspects of this handgun might surprise you.
