Description
Is the Glock OEM Extended Slide Lock Spring 3-Pack Worth It?
Yes, absolutely. For $12.99, you get three factory-original slide lock springs. This isn’t an upgrade part; it’s a critical maintenance item. The slide lock spring, also called the slide stop spring, is a high-stress component that controls your slide lock lever and magazine release tension. When it wears or breaks—and it will—your gun stops running. Having spares on hand means you’re back in action in minutes, not days. Every serious Glock owner should have this in their parts kit.
What Makes This Glock Slide Lock Spring Stand Out?
- Glock OEM Specification: This is the exact spring from the factory. Why it matters: It guarantees perfect fit, tension, and reliability in your firearm, with no guesswork.
- 3-Pack Quantity: You get three identical springs. Why it matters: One for immediate repair, one for your range bag, and one for the parts bin. It’s cost-effective insurance.
- Music Wire Spring Steel: Made from precisely tempered steel. Why it matters: It provides consistent, long-lasting tension and resistance to fatigue under repeated cycling.
- Full Generation Compatibility: Works in all Glock Gen 1-5 models in common calibers. Why it matters: One part number covers nearly your entire Glock collection, simplifying your inventory.

Pros & Cons
Pros:
- Pure Glock factory quality ensures perfect function.
- The 3-pack offers exceptional value and prepares you for multiple failures.
- Universal compatibility across generations makes it the only spring you need to stock.
Cons:
- Installation requires a punch and pinning out the trigger mechanism housing. It’s not for beginners.
- This is just a spring. If you’re looking for a performance upgrade, check our Triggers category instead.
Who Should Buy the Glock Slide Stop Spring?
Buy this if you maintain your own guns. It’s for the shooter who has a punch set and knows how to detail-strip a Glock frame. Competitive shooters with high-round-count guns need these. Instructors and anyone who relies on their Glock should have at least one spare. If you’re building a P80 or doing frame work, this is a required component. It’s not a glamorous purchase, but it’s a fundamental one. Consider pairing it with other common wear items like trigger springs or Glock Switches for a complete refresh.
Frequently Asked Questions
Is this the same as the slide stop spring?
Yes. Glock calls it the slide lock spring (Part SP00056). It’s the same component. It applies tension to both the slide lock lever and the magazine release.
Will this work in my Glock 43X/48?
No. The single-stack Slimline models (G42, G43, G43X, G48) use a different, smaller spring. This SP00056 is for double-stack models (G17, G19, G26, G34, etc.).
How often does this spring need replacement?
There’s no set round count. It’s a wear item. Inspect it during deep cleans. If the magazine release feels sloppy or the slide doesn’t lock back reliably, check this spring first. Having a spare means you never have to find out the hard way.
Do I need special tools to install it?
You need a 3/32″ punch to drive out the trigger mechanism housing pin. You’ll also need a small hook tool or dental pick to remove and install the spring itself. If that sounds unfamiliar, have a qualified armorer do the work.
