The FNX Magazine Base Pad Extension adds two and a half (2.5) rounds to the existing standard capacity magazine for the FNX 45 model pistols. “Why is it 2.5 rounds, not 2 and not 3?” you ask? The Apex Tactical mag extension leaves enough space for 2 additional rounds to be loaded, but also enough space for the stack to further compress the magazine spring to allow a fully loaded magazine to be seated with the slide in battery.

Expected Results:

• 1) Adds 2.5 rounds of additional capacity to your magazine.
• 2) Maintains function of the slide lock after the last round is fired.
• 3) Finger grooves on the perimeter and front corner finger grooves make gripping the base easy.
• 4) Machined from aluminum and Black Type III Hardcoat Anodized for durability
• 5) Single Set screw keeps mag extension snuggly in place and allows for ease of disassembly
• 6) Easy to install

Applicable To What Guns:

• For use with standard capacity magazines for FNX 45
• Please Note: Not tested or approved for use with 10 round magazines
