G17 Gen3/SCT Frame/Delta Team slide

I’ve been having this issue where after firing a round the spent casing won’t eject. I changed the extractor to a glock OEM with a new plunger and spring it happens less often but still the same issue. Tried multiple mags of different makes with no luck. No optic installed. Used dummy rounds to replicate what the failure looks like. Spent casing sits in barrel causing failure to feed the next round. The casing doesn’t get stuck either, when I eject the mag and tilt the barrel it just slides out. Any ideas would be appreciated!
