Just wanted to share what I learned about my brand new Glock 23 Gen 4 when using a Weapon Light. I changed Mag Springs to Wolff +10 before ever shooting it, almost out of habit. Have had good results with Wolff Mag Springs in the past with other Glocks and guns and will continue to use them in them. However, with a Weapon Light attached to this brand new G23 Gen4, I had multiple FTFs in each Mag about the 4th round with Fed 180g HST ammo. Happened with X300, TLR-1s and TLR-3. Went back to OEM Mag Springs and gun is now running 100%. BTW, gun ran 100% with no light attached and Wolff Springs, just not with light on it. Seems like the Wolff Springs were too good and pushing next round up too fast with light attached and actually slowing down the slide, thereby causing a FTF. The slide would just sit there behind the Mag out of battery and the Mag would look normal with cartridges sitting in normal position. I have the new RSA and latest Ejector, #9 Followers on the Mags. The gun would have worked fine out of the box if I wouldn't have changed the Mag Springs when it wasn't needed.
