Product Details
This is the factory spring that keeps your slide locked back after the last round fires - a small part that matters when you're at the range or in a defensive situation. It fits Glock 17, 20, 21, 22, and 31 models. If your slide isn't staying back like it should, this OEM replacement gets you back to reliable function. It's genuine Glock, so you know it'll work the way your gun was designed to.
