Yes, I think so. In Hokkaido, what I did was I placed a Bartoli pistol on the ledge near the Gas Tank where the Handyman smokes.
Nailz, the helicopter pilot, sees the gun, goes back up and calls a guard. I then grab the pistol and run almost all the way to the door that leads to the access area for Staff Quarters and the Morgue and place this same pistol on the ledge there.
The guard that comes down walks all the way to the pistol’s new location and does the pick-up routine and does not stop near the Gas Tank at all.
On second thought I might have done it as Nailz was going back. May have to test again.
