When you own an FN 510, sticking with OEM magazines just makes sense. FN America engineered this pistol around its own cartridge-specific geometry, and these factory mags are built to match that exactly. You get the same precise fit and feed angle as the mag that shipped in the box, so there is no guesswork about compatibility.
The body is nickel-coated steel, which gives it real durability and good corrosion resistance for a mag that might live in a range bag, a vehicle, or on a duty belt. Steel feed lips keep their shape under repeated loading and unloading, which matters a lot over the long run since bent or worn feed lips are the number one cause of magazine-related feeding issues. A low-friction polymer follower and steel wire spring round out the internals and work together to keep rounds moving up cleanly and consistently.
The finish combination here is part of what makes this mag a little distinct visually. The nickel-coated steel body gives the magazine that silver appearance while the flush-fit polymer baseplate is black, matching the overall look of the FN 510 frame. It sits flush with the grip for a clean, snag-free profile.
This 10-round version is what FN offers for owners who need a reduced-capacity option. It is the same quality and construction as the full-capacity mags, just built to a 10-round spec. It functions and fits identically to the higher-capacity options, so you can mix and match in your range bag without any issues.
Yes, this FN America magazine is designed to fit the FN 510 platform and is compatible with both the 510 Tactical and 510 MRD models. The frame and magazine well dimensions are shared across the FN 510 series, so the fit and function are the same regardless of which variant you have.
The construction and materials are identical between both options. The 10-round version is simply a shorter magazine with reduced capacity, while the 15-round mag is the standard flush-fit option that ships with most FN 510 pistols. Both feed the same 10mm Auto cartridge and use the same steel body, feed lips, and polymer follower design.
This is a genuine factory magazine made by FN America, part number 20-100733. It is not a third-party or aftermarket product. You are getting the same magazine that FN builds to spec for the 510 platform, which means identical fit, feeding geometry, and quality control.
The silver appearance comes from the nickel coating applied to the steel magazine body, which provides corrosion resistance and a low-friction surface. The baseplate is a separate black polymer component. It is an OEM design choice by FN America and is not a cosmetic upgrade or aftermarket modification.
Most people find two to three magazines to be a practical minimum for range use, giving you enough loaded mags to run a decent training session without constantly reloading. Having at least one extra beyond what the pistol shipped with also gives you a ready backup if one ever needs to be retired due to a worn spring or damaged feed lip.
