Why Choose This FN Factory Magazine
OEM reliability you can trust: Correct feed-lip geometry, spring tension, and follower design ensure consistent chambering and last-round lock-back in FN 510 platforms.
Stainless-steel strength: The robust tube resists dents, corrosion, and hard use—from long range days to wet weather and daily carry.
Flush polymer floorplate: Low-print, flush-fit base keeps the grip’s footprint minimal for discreet carry while enabling positive seating on reloads.
Compliance-friendly capacity: The 10-round configuration supports carry and ownership where higher capacities are restricted (verify local laws).
Optimized for 10mm: Designed to handle the 10mm Auto’s longer cartridge and sharper recoil impulse for reliable feeding across popular bullet profiles.

Real-World Advantages
Carry-ready design: The flush floorplate helps reduce printing while still offering a full-firing grip on the FN 510 frame.
Training efficiency: Stainless body and tuned spring endure high round counts and frequent loading cycles—ideal for multi-mag range sessions.
Duty/home defense confidence: Factory tolerances minimize variables that can cause stoppages—critical when reliability matters most.
Organize loads: Keep dedicated mags for defensive JHP and FMJ practice; mark baseplates for quick ID during classes.
Best Practices for Reliability
Initial check: Inspect feed lips, follower, and tube for debris; wipe down before first use.
Load properly: Seat each round fully to the rear to maintain consistent stack geometry.
Rotate mags: Cycle through your magazines to balance spring wear and verify function across your set.
Use quality 10mm ammo: Stick to SAAMI-spec 10mm Auto from reputable manufacturers for consistent results.
Care & Maintenance
Periodic cleaning: Disassemble per FN guidance; remove unburnt powder, dirt, and moisture from the tube, follower, and spring.
Run nearly dry: Avoid heavy oil inside the mag body—excess lubricant attracts grit and can slow follower travel.
Post-carry wipe-down: After humid or rainy carry, wipe the stainless tube and floorplate to preserve finish and function.
Safety & Compliance
Follow all federal, state, and local laws regarding magazine capacity, transport, and storage.
Ensure the firearm is unloaded before inserting/removing magazines or performing maintenance.
Confirm reliable function at the range before adding any magazine to your defensive rotation.
