  • Great ergonomics
  • Reliable design
  • Interchangeable backstraps
  • Pricey
Editor’s Note:

The FN 509 is designed to be a duty weapon. This striker-fired 9mm is a nice gun packed with small features that add up to a lot. From interchangeable backstraps to an accessory rail, this gun has enough going for it to justify the price. While not a budget option, it’s a mid-tier that offers reliability and smooth shooting.

The FN 509 is a polymer pistol with a weight of around 26 ounces and a length measuring 7.4 inches. It features a fixed 3-dot sight system with combat-style sights and a capacity of 17 rounds (or 10-round mags available for states that require that). The trigger pull comes in around 5.5 to 7.7 pounds and it feels smooth while shooting. The gun is ambidextrous right out of the box, great for those lefties! The FN is a nice pistol that is worth the money.

Glock 19

Glock 19


Glock 19 is the most proven compact semi-automatic handgun on the market today. Chambered in 9mm Luger, the Glock 19 is a versatile compact version of the standard Glock option.  It’s great for use as a backup weapon, concealed carry, or service pistol.  The Gen 5 in particular has made some great improvements which include an ambidextrous slide stop lever, flared mag-well, and upgraded barrel design, just to name a few. The G19 has been a favorite amongst police agencies and military units and for good reasons. This gun is simple to operate and easy to maintain, making it a great first gun, CCW, or home defense weapon.
