I am having the same problem. I started a thread on it above. I did note that when the slide sticks the barrel is fixed and has no "play" in it like it would when it is locked rearward by the slide lock. 10 weeks for a carry permit. Now another possibly 6-7 weeks to get this looked at. Not happy. Mine is sticking often enough that I have no doubt they will be able to replicate the problem though. Can barely get through a magazine without it happening.
