yeah that sounds like a glock chamber alright.
Might not be that the SL chamber itself on the is too tight but that the transition shoulder from ramp to chamber needs polishing. Storm Lake might offer to do this to make it right.
Edit: sorry I just re-read your post. If the round is factory load and it gets stuck half way in even when manually feeding it outside the gun then that's clearly a chamber problem.
