In the near future, I will be looking at my first potential purchase of a used Glock (I've always bought new) and I'm curious as to what you would specifically look for when inspecting used Glocks (or any gun for that matter) prior to purchase. I will probably not have a chance to shoot this gun before making my decision. My checklist currently includes: 1. Visual inspection of exterior for damage, scars, wear. 2. Dry fire for function. 3. Load mags for function. 4. Cycle loaded mag through gun by racking slide. 5. Field strip 6. Inspect internals for cleanliness, wear. 7. Check documentation of test fire date, S/N, matching numbers 8. Check for aftermarket internals. Your suggestions to add to this list will be appreciated. Wanna kill these ads? We can help!
