Offering concealability and reliability, the new FN 503 shares the lineage of their full-sized pistol line but comes in a micro-compact format.
Introduced in March, the striker-fired 9mm borrows the design, performance, and reliability standards of the company’s popular FN 509 series folded into a pint-sized single-stack optimized for concealed carry. The resulting FN 503 is both slim and trim. Currently the company’s smallest handgun, the 503 has a smaller profile than the FN-S Compact and FN 509 Compact.
Specifically, the 3.1-inch barrel contributes to a 5.9-inch overall length. Height is 4.6-inches with the flush fit magazine while width, over the surface controls, is 1.1-inch. To put that in context with contemporaries, it is roughly the same ballpark size as the Glock G43 or Sig P365.
While overall width is listed as 1.1-inches, it should be noted the slide is slimmer than that.
When compared to legacy FN products, the gun is smaller than a Hi-Power and is more comparable to an FN 1910/Browning M1955, one of the most classic concealed carry pieces of the 20th Century.
Ideal for the consumer market as a carry
