I used to bring 4 or 5 but as I get older and read about accidental discharges more, I find that only having 2 or 3 guns to clean allows me to bring one down stairs (cleaning area) at a time This seems to help me with makeing sure there cleared and focus on just a couple instead of having a bunch to do one right after the other. So these days 2 or 3
Let's see, yesterday we took my Lionheart9, nagant revolver, Ruger Vaquero, G19, Walther G22 and my son-in law rented an M&P9 to try, so it was busy but fun. Generally, we take a couple of pistols and a rifle.
