I installed an SCD on my Glock 30S yesterday and found when I went to function check it that when I pull the trigger and then cycle the slide while holding it, the trigger does not reset, but it does reset if I dry fire and release the trigger before cycling the slide. I removed the SCD and replaced the factory backplate and the issue remains.

I’ve detail stripped it, replaced the recoil spring assembly, lubed everything, and looked it over to the best of my ability and I’m at a loss for what the issue may be.

Anyone ever seen something like this before?
