FN 503 Variations & Comparables
The Sig P365 is an impressive micro 9mm with a great track record. This gun is a popular subcompact semi-auto pistol, designed for CCW and self defense. Some of it’s key features include a 10-round capacity, which is higher than many of its competitors, compact and modular, has XRAY3 Day/Night sights providing visibility in low light conditions, and ambi controls. We’ve tested this gun time and time again. As our writer puts it, “The rest of the industry has had a couple of years to catch up but the P365 is still an impressive micro 9mm that is super popular as a CCW option.” – Travis Pike
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.
final verdict
“FN never really makes a bad gun and the FN 503 is no exception. Outside of a short break-in period, it has been reliable and great to shoot. The truly amazing trigger makes this a much nicer gun to shoot out of the box than many other options on the market right now.” – David Lane
