The FN509 is a great full-size, mid-size 9mm pistol. They have recently release the 510 and 545 which are the 10mm and 45acp rounds. The FN509 is what I picked up over new years weekend. I purchased this one at Bass Pro Shop for 699.99 and it came with the Viper Vortex. Other features for this particular firearm is:
With the FN 509® MRD Optics Ready Semi-Auto Pistol with Vortex® Viper RDS you get full-sized performance, in a midsized carry package, topped off with an excellent red dot sight — The Vortex Viper. While most of the industry would call this size a compact pistol, FN is more accurate in calling it midsized. Featuring a cold hammer-forged stainless steel barrel with a recessed crown, and a polished feed ramp and chamber, this pistol promises optimal accuracy and ultrareliable performance. The slide features aggressive slide serrations for improved manipulation. The slide also hosts an external extractor and a loaded chamber indicator. The short, easy-concealing grip is textured for enhanced shooting control, and it has interchangeable backstraps for customizable comfort. Other features include a MIL-STD-1913 accessory mounting rail, improved flat-face trigger, and ambidextrous slide stop lever and magazine release. A low-profile, high-visibility front sight delivers intuitive acquisition. Includes 2 magazines.

This firearm is full-size and I wanted another full-size the extras were just topping on the cake. I tried to purchase it over Christmas break but was unable to get it for the timeline. I have yet to be able to shoot the pistol but maybe in a few weeks I will be able to get to a range. I am in a new state and still learning everything.
The 509 of mine is a 4in barrel, 17rnd mags, night sites and it can be had for $729 at bass pro for the one I got. It can be found cheaper at other stores and in many different configurations.
