Question about Book of Mormon in Chicago (Spoilers)

I am finally seeing Book of Mormon in Chicago this week. What has kept me from the show is knowing there's a loud sudden gun shot in it. I have a PTSD involving guns plus sensitive ears. You guys have helped me in the past. My question: is the gun shot recorded or an actual blank fired on stage? I have looked at the script and know where it happens. This might strike some as too much but gun shots do a number on me. I prefer recorded (as in Eclipsed or Hamilton). I'm working on it. Thank you so much!

Thank you so much! That helps a lot.

Might be important to note that although the gunshot in BoM is not jarring like Les Miz or Phantom, visually it is pretty graphic. It's definitely one of the most shocking moments I've seen on stage. Someone who has PTSD might have trouble with it.

Phantom, I really appreciate the warning. Thanks!
