Sometimes if the recoil assembly is just a tad off where it belongs it won't go on. Remember the assembly is a bit off center. Should be parallel to the slide. Move it a bit and try again. I also sometimes have to kind of tickle the trigger to get the slide all the way on. Give it a twirl and get back to us.
Welcome to the asylum. We kind of like it here.
