Stick with factory springs
First off the springs have an odd twist side twist unlike the factory Glock springs which will slide in and out of the mag body smoothly. Because the spring is not straight like the factory originals, the follower tends to pop of when pulling the spring off but more importantly when being inserted after cleaning, which leaves me wondering whether it could cause a malfunction later on. On a side note, this spring does allow factory +2rd extenders to properly lock in place. The base seems to be much smaller and twisted sideways thereby not allowing the tab under the floor plate to catch on correctly. I'll be returning these!
