Went firing my Gen.3 G23 this evening. I've had the Glock for about a year now and have put about 1500 rounds through it (Bought brand new). It is cleaned every time I fire it (1 or 2 times per month). I was firing the normal Winchester 165gr. FMJ target/range ammo at the time. This is not unusual ammo for me. Ive never fired reloaded or +p ammo through my Glock. Fired about 25 rounds this evening and was firing at pumpkins in the desert. fired one round and then pointed the weapon down at the ground. Next thing I know, my weapon feels feather light. I look down and my slide is laying in the sand.... OH NO!! ;P I inspect the frame and my slide lock is now missing from the weapon along with the slide lock spring. I belive a small piece of the slide lock spring is left in the frame so I suspect a broken slide lock spring was to blame, but I am no Glock armorer. This is my daily carry pistol so I am extremely disappointed! Has anyone ever seen this before? Is this a rare anomoly? Any advice? Let me know your thoughts.
