Magazine Base Pad Extension for FNX 45

Description

Designed specifically for the FNX 45, this magazine base pad extension adds a functional 2.5 rounds of capacity to your standard factory magazine. The unique half-round gain is not a typo — it provides space for two additional cartridges while leaving enough room for the magazine spring to compress fully. This ensures a fully loaded magazine can seat easily with the slide in battery, preventing the common frustration of a stubborn mag when you need it to lock in.

Machined from solid aluminum, the base pad is built to withstand regular use at the range or in training. It comes in two durable finishes: a Black Type III Hardcoat Anodized option for maximum wear resistance, or an FDE Cerakote finish that closely matches the factory FNX 45 frame color. The FDE uses a commercially available Cerakote standard (H-267 Magpul Flat Dark Earth) so you can color-match other accessories if needed.

Key benefits and specs:

• Adds 2.5 rounds to your standard FNX 45 magazine — enough for two more cartridges plus spring compression clearance for reliable seating with the slide forward.
• Slide lock function is preserved after the last round is fired. The included Extra Power Magazine Spring ensures the slide locks back consistently on an empty magazine.
• Finger grooves on the perimeter and front corner make it easier to strip a stuck magazine from the magwell under stress or with gloved hands.
• Machined notches on the bottom face allow you to color-code your magazines for quick identification and tracking (visible only on the Black anodized version).
• Single set screw secures the base pad snugly to the magazine floorplate, and makes disassembly straightforward for cleaning or spring replacement.
• Easy installation — no permanent modifications to your magazine required.
• Fitment: Works with standard capacity FNX 45 magazines only. Does not fit 10-round or restricted-capacity magazines.

Important compliance note: This product is not for sale to California, Oregon, Rhode Island, or Washington residents due to state capacity restrictions. If you are a customer in a restricted state, please check your local laws before ordering. For customers in other states, this base pad is a straightforward way to add practical capacity without compromising the reliability of your FNX 45.
