For most of my life, (meaning when I wasn't vacationing in Canada) I've been able to check weapons (and lights, locks, the stove, toaster and coffee pot) as the last thing before I turned the lights out. So no, if I had to reach out in pitch darkness and pick up a weapon, I wouldn't check it.
Thinking about it, I might check it if I had the opportunity to turn on a light, but not in the dark.
Hearing a bump in the night in the darkness is not the time to learn a new skill, and tactile press checks are not a skill I've trained, because I've always had this question about it.
