FN 503 For sale online Semi-Auto Pistol – Black

FN 503 For sale online is the highly concealable micro-compact pistol perfectly suited for concealed carry. With a legendary reputation of FN durability to uphold, the compromises in shootability, accuracy and reliability with slim CCW handguns are solved.

FN chose beefy metal parts and a better balance point to a rigid frame on a slim slide, tuning out felt recoil. Benefits of an oversize extractor and slide stop ensure failsafe feeding and control, with full height grip stippling locking into the hand to reduce muzzle flip.

The FN 503 delivers the confidence and repeatability for serious shooters who expect more from their concealed carry handgun. Accuracy is delivered with a best-in class all-metal trigger that breaks cleanly at ≈5.5lbs, with a crisp sight picture from metal, snag-free 3-dot sights.

Available in flat dark earth and black, the advanced ergonomics of the FN 503 allow instinctive and fast changes between the included 6-round and 8-round magazines.]

A little pistol with a solid pedigree, the new FN 503 9mm sub-compact lived up to its family name in testing and is a solid everyday carry gun.

Introduced in early 2020, the striker-fired polymer-framed FN 503 borrows the design, performance, and reliability standards of the company’s rugged FN 509 series. FN just folded it into a downsized single-stack package.

The result is slim and trim. It holds down the title as the company’s smallest handgun, beating out the legacy FN-S Compact and FN 509 Compact.

When it comes to dimensions, the FN 503 has a 3.1-inch barrel and 5.9-inch overall length. Height is 4.6 inches with the flush-fit magazine. The width over the surface controls is 1.1 inches.

The FN 503 is only offered in 9mm and is short, trim and has a 6+1 capacity.

Addressing the elephant in the room, it compares well to the Glock 43. In fact, it is just slightly shorter. They share the same standard magazine capacity, but the FN-made gun comes with steel rather than plastic sights.

Glock’s single-stack 9mm runs 6.26 inches overall due to a 3.41-inch barrel. However, the G43 is a hair shorter than the FN 503, which stands 4.25 inches tall with a flush-fit 6-shot mag inserted.

FN 503’s included extended 8-shot mag with a grip sleeve adds about an inch to the height. It is an apples-to-apples comparison to the G43 with aftermarket tactical mag extensions. Gratefully, FN ships the 503 with one magazine of each length.

Our test FN 503 hit the scales at 23.5 ounces with a loaded chamber and a similarly topped-off 6-round mag inserted. It was 25.2 ounces with the longer 8+1 set up.

Disassembly is a bit “old school” because there is no dedicated takedown lever. The barrel has a recessed target crown and a polished chamber and feed ramp. Also, note the extended slide stop and fenced-off magazine release with a raised texture.

ON THE RANGE

Reliability was impressive on the FN 503. Running a variety of loads from Federal, IMI, PMC, Winchester, and Wolf, we clocked just over 1,000 rounds through the short-framed gun. Our ammunition ranged between 115 and 147 grains and included both range and personal protection loads.

The majority of that ammo, about 75 percent, was American Eagle red box FMJs. We logged one jam during testing – ironically on the second round fired – but feel it was due to an improperly inserted magazine.

The FN 503 has a steel trigger with a safety lever inset. It has what is billed by the company as a 5-to-7-pound trigger. We found ours breaks at an average of 5.2 pounds, which is nice for a factory striker-fired trigger pack.

We had an experienced 12-year-old junior shooter put about 200 rounds through the FN 503 using the shorter mag and he had no problems. The full-length steel chassis lends to less “flex” in the firing cycle than pistols with shorter rail inserts.

Despite its short barrel, the gun shot relatively flat and proved capable of keeping on center mass out to 25 yards with no issues. At 15 yards, 8-inch action pistol plates were on the menu even with a sight radius shorter than the length of a Twinkie.

CARRY

First fielding the test gun in May, we have carried the FN 503 often since then. We probably clocked in nearly 300 hours with the pistol. We started with some repurposed holsters at first but were able to upgrade to purpose-built leather gear from DeSantis Gunhide. This included one of their Inside Heat models for IWB and a Mini Scabbard for OWB

The Desantis Mini Scabbard has an adjustable tension device while the Inside Heat has a reinforced top to ease re-holstering. Both were comfortable with the FN 503, although we put more time in with the Inside Heat, typically in a 2- or 3-o’clock position.

The weight and size profile of the FN 503 unsurprisingly reminds us of the G43 while carrying. The pistol provides just enough heft on the belt to remind you that it is there without dragging you off course as you walk or printing excessively.

The FN 503 was easy to carry both while out and about and around the house. It easily keep along while performing outside tasks such as stocking hay for the winter.

IN THE END

The FN 503 performed well and met expectations when it came to reliability and durability. It is intended as a discreet EDC that brings more to the party than a .380 or .32 ACP-chambered cricket, and it carries well. While having more rounds on tap than your typical snub-nosed revolver – and with a faster reload – it squares with guns like the Glock 43 and S&W M&P Shield 9 in capacity and intended use.

While on par with the G43 and S&W Shield, the FN 503 suffers a bit in the capacity department when compared to the Springfield Hellcat or Sig P365. Nonetheless, it has a lot to offer.

About the worst brick we can throw at it is that the latest generation of micro-compact 9mm pistols, such as the Sig Sauer P365 and Springfield Armory Hellcat, surpass the FN 503 in the ammo capacity department. Further, competitors like the G43 have a ton of aftermarket upgrades floating around while the FN is more neglected.

Still, the gun checks a lot of boxes and is an easy call for someone looking for a dependable carry gun without a lot of frills. That is especially if they are already FN fans. However, even if they aren’t already fans, they likely will be after picking up one of these.
