I have a Gen 4 G19 and I can not for the life of me get the pin that holds the back strap in once I add one of the back straps. Has anyone had this issue??
They come with the correct sized "punch" on the thing that holds all the backstraps in the box, as well as a place on it that holds the longer pin for the backstraps. Best way to align it is with the tool still inserted, push out the tool with the longer pin used for the backstrap.
