How about the grittiness and sponginess compared with the regular M&P? I remember it feeling like I was pulling the trigger across sandpaper into a sponge, and there were so many catches and clicks I couldn't determine when it reset. Bout the AEK and firing with snap caps went to a sharp click on pull and a sharp click on reset.
So is the stock CORE trigger like the AEK in that regard? Or is it like walking across the floor in a haunted mansion like the original.
