With the slide off the pistol and the striker locked back in the channel, shake the slide. Can you hear the striker rattle back and forth? If not something is binding it.
When you looked at the striker were the spring cups seated properly? Make sure that the point where the spring cups join is not over the end of the spring where the spring actually starts.
Also check the channel liner for any rough spots, if you can get a light down in there.
When you press on the striker safety block does it move up and down freely?
