Gary, the Beretta is a safe design that does not allow you to cycle live rounds from the magazine to the chamber manually.
To unload, you jack the round from the chamber and then remove the rounds from the magazine by depressing the device which retains unfired rounds in the magazine. Irritating at first, the safest and best way to fly once you get used to it.
Remingtons (870's and 1100's, not sure about 11-87's) can be unloaded like this, though you need to unload the magazine first, as described above. They are also not as "slick" as the Beretta.
I have rarely shaved plastic from shells loading the Remingtons, never the Beretta.
Another plus to the auto - I put three 1&7/8's oz 3" loads through mine as fast as I could aim and fire yesterday. Recoil was very tolerable.
What is that O/U you shoot, anyway?
