Mom passed away 12-31-11 and I just to opening the safe and found dads loaded Glock, he passed away in the early 90's after a long illness. A few days back I registered on Glock Talk to find its value. The clip being loaded so lone it lost some of it spring. Now the empty clip will not lock open the slide. How do I remove the clip spring and stretch it? Wanna kill these ads? We can help!
