FN 20100732 510 Replacement Magazine 22rd Extended Floorplate 10mm Auto Fits FN 510 Tactical Stainless/Black Stainless Steel

The FN 510 Tactical 10mm Auto 22-round extended magazine is built for shooters who demand serious capacity and reliable performance in a full-size tactical pistol. If you run an FN 510 Tactical and want to maximize rounds downrange without sacrificing control, this factory magazine delivers the extended grip real estate and smooth feeding you need for rapid follow-ups in self-defense or competition scenarios.

FN engineered this magazine with a purpose: the extended polymer base plate does double duty, giving you extra real estate to grip and improving your ability to manage recoil between shots. That matters when every fraction of a second counts. The stainless steel body shrugs off the elements and holdup to hard use in the field or at the range. A corrosion-resistant finish means you won't be babysitting your magazines—they'll stay ready.

Reliability is the baseline here. Low-friction polymer followers paired with steel wire springs and hardened feed lips keep rounds feeding smoothly, shot after shot. Whether you're practicing defensive drills, running competitions, or training to stay sharp, this magazine works without drama. FN's reputation for durability in duty-grade equipment carries through to the accessories—this is the real thing, not a compromise.

Will this magazine work in harsh conditions?

Yes. The stainless steel construction and corrosion-resistant finish are designed to handle field use in tough environments without degrading performance or requiring constant maintenance.
