I have been listening to the shows in order and just so happened to reach this show when it was the show of the week - go figure.
This is one of my favorites so far (out of the 41 I've heard) because it was one of the more believable and suspenseful episodes. The actors did a great job with their tones and conveying their fear and desperateness.
Was the trigger on the gun really broke or was saying it was enough to make them give up on the idea of using the gun? I rate this one a 4.
