Apex Extra Power Magazine Spring Set

Description

For shooters who demand reliable slide lock back and consistent feeding under high-round-count conditions, the Apex Extra Power Magazine Spring Set delivers the mechanical advantage your duty rig or competition setup requires. These springs are engineered specifically to increase cartridge lift force during the feeding cycle, reducing the likelihood of a sluggish or incomplete feed when the magazine is under spring tension. The improved upward pressure also ensures the slide lock engages positively when the magazine runs empty, eliminating the frustration of a slide that fails to stay open on an empty chamber.

Each spring is precision-formed from Rocket Wire, a high-tensile material selected for extreme durability and consistent performance over thousands of compression cycles. This material choice matters for shooters who run high-volume training sessions or carry spare magazines in demanding environments. The springs are manufactured in the USA to Apex’s exacting specifications, ensuring each unit meets the same quality standard as the rest of your upgraded platform.

Confirmed fitment for the following magazine configurations:

• FNX-45 magazines fitted with an Apex Magazine Extension
• Apex 19-round magazines for SA-35 Series Pistols

Important fitment note: These springs are not recommended for use with the Apex 17-round magazine. Use only with the magazine types listed above to ensure proper function and reliable slide lock performance.

At just $25, this spring set is a straightforward upgrade for Springfield SA-35 shooters or FNX-45 users who have already invested in an Apex magazine extension. It addresses two common failure points in high-use magazines: weak spring pressure causing nose-dive or short-stroke feeding, and inconsistent slide lock engagement during emergency reloads. For competition shooters, this means fewer malfunctions during a stage and more confidence in your reloads. For those building a serious duty rig, it adds a layer of mechanical reliability that can make the difference when every round and every second counts.

Replace your factory springs with these when you notice a drop in feeding consistency, or install them as a proactive upgrade during a full magazine rebuild. The extra power spring compensates for the added weight of extended base pads or high-capacity bodies, keeping the follower moving smoothly and the slide lock activated reliably. Whether you are stacking rounds for a match or stocking spare magazines for a patrol setup, this spring set delivers the tangible performance benefit of consistent, positive magazine function.
