Upgrade reliability where it matters most—inside the magazine. The Glock Magazine Spring (Fits Glock 17, 18, 34 – All 17-Round Magazines) 33510 is a precision replacement spring designed to restore strong, consistent feeding performance in your factory 17-round mags. Whether you’re maintaining duty gear, refreshing range magazines, or bringing well-used mags back to peak function, this magazine spring is a simple, high-impact component that helps keep your Glock running smoothly.
Why a Magazine Spring Matters
In any semi-automatic pistol, the magazine spring is a primary driver of reliability. A tired, weakened, or worn spring can contribute to:
Slow or inconsistent follower movement
Feeding hesitation
Failure-to-feed issues (especially under speed)
Reduced reliability with heavier bullets or defensive loads
Inconsistent slide lock behavior (depending on follower and wear)
Replacing the spring is one of the smartest, most cost-effective ways to maintain the performance of your magazines—especially if they’ve seen years of training cycles, carry compression, or long-term storage loaded.
Designed to Fit Glock 17-Round Magazines
This replacement spring is specifically made to fit all Glock 17-round magazines for the following models:
If you rely on standard-capacity 17-round mags, this spring is the correct fit for refreshing your magazine internals and restoring the firm, positive upward pressure necessary for smooth and consistent feeding.
Restore Feed Consistency and Improve Function
As magazines age, springs can lose tension from repeated compression cycles and extended use. Installing a fresh spring helps ensure:
Reliable cartridge presentation at the correct angle
Consistent feeding under rapid fire
Better performance in training and competition
Improved consistency when magazines are kept loaded
A renewed “snap” in follower return and top-round retention
If your magazines feel sluggish when loading, don’t lock the slide back reliably, or feed less consistently than they used to, a spring replacement can often be the fix—without needing to replace the entire magazine body.
Ideal for Maintenance, Training, and High-Round-Count Use
Many Glock owners rotate magazines for duty, concealed carry, training, and competition. Over time, springs in heavily-used range mags can wear faster than those in carry mags. This Glock-compatible magazine spring is an excellent option for:
Preventive maintenance schedules
Refreshing older or frequently used magazines
Rebuilding training magazines for consistent drills
Keeping spares on hand for quick repairs
Armorers and departments managing multiple magazines
If you run frequent classes, shoot matches, or practice regularly, keeping replacement springs available is a practical way to reduce preventable malfunctions.
Easy Upgrade with Big Results
Replacing a magazine spring is straightforward for most users with basic tools and careful handling. Once installed, many shooters immediately notice improved feel and function—especially in older magazines that have been loaded and unloaded countless times. The result is increased confidence that each magazine will perform when it counts.
