This is a Glock 19/23 magazine spring. 

You don’t need to settle for an off-brand aftermarket magazine spring for your Glock 19/23, since you can order this factory OEM spring from The Mag Shack! 

This is the same high-quality steel spring found in your factory Glock magazine that will keep it running smoothly for many rounds to come. 

There isn’t much more to say about it…it’s a spring! However, it’s THE spring you want if you’re replacing the one that’s currently in your magazine.

It can never hurt to have spare parts lying around. Why not add a few springs to your cart?
