(I added the "Clip" part to annoy and grab your attention.) Most of us want to save money, so instead of buying $20-40 on a new complete Glock magazine I just want to buy parts for my old mags. So my questions for those whose on a tight Glock budget: 1. Which magazine part have most GlockTalkers replaced? 2. How much is a reasonable price for those parts? Thanks!
