My 9mm Trojan would not feed from dropping the slide stop, EVER. The part of the slide that picked up the round was beveled. So, it would hit the round even higher than normal. This would cause severe nose diving. It was a known issue, and a well-known gun Smith told me they have a fix where they weld and re-cut the slide so that it is square. I’m not sure if they were all made like that, mine was an earlier model.
