I had a 3.5 lb connector in my G17 frame. I sent my G17 to Glock GA to get a new 3rd gen frame. When the gun came back a few weeks later, the 3.5 lb connector came back separate from the new 3rd gen frame. I mmediately installed it into my new 3rd gen frame. What is it with Glock? Do they disapprove of the 3.5 lb connector?
