I forgot to post that with the stock guide rod I still have early lock back with my Dan Wesson 10mm. I double checked that the rounds are not hitting the slide stop, so the slide stop is jostling upwards and catching the slide notch.

I read about how the barrel link rides on the slide stop, so the barrel is directly imparting force on it maybe. I need to probably dimple the plunger/detent on the slide stop to fix it.
