My Ruger SP101 357 magnum, and my Sig P250 in 357 sig. They are loud in the indoor range.
A guy next to me was shooting a Glock 20 with some handloads. That sucker was LOUD! It was actually distracting me while I was shooting. I finally leaned over while he was reloading and asked him what he was shooting over there.
"Give me liberty, or give me death!"
