Glock 17/19/26/34/45 Slide Lock Spring Features The Glock Slide Lock Spring is manufactured to the same high standards in material and workmanship as the spring that ships factory-installed across the Gen5 lineup including the G17 G19 G19X G26 G34 MOS G44 G45 and G45 MOS. The slide lock spring is responsible for holding the slide lock lever in position which controls whether the slide locks back on an empty magazine. A tired or broken spring can cause the slide to fail to lock back which is a reliability issue shooters notice quickly during training or duty use. Replacing it with a factory-correct spring restores that function without introducing fitment problems. Because this part is genuine Glock equipment it installs exactly as the original did without modification to the frame or slide lock lever. Keeping a spare slide lock spring on hand is a low-cost way to address a developing reliability issue before it affects performance on the range or in a defensive situation. The small part is easy to store and simple to swap during a routine detail strip. This Glock Slide Lock Spring is a practical maintenance item for Gen5 Glock owners available for sale at GrabAGun.
