two Beretta shotguns - questions

[max popenker]

hello
can anybody tell me anything abou the foloowing shotguns:

beretta 1201FP
and
beretta M3P

i believe that both are semi-automatic but i do not know what actions those shotguns used (gas, recoil).
any other info also will be appreciated.

thanks in advance.

The 1201FP uses a short-recoil inertia system like the Benellis do, but the M3P is one of these "dual"-system firearms that can be used as either a pump-action or a short-recoil semi-automatic; to switch from one to the other, you twist a little eared collar up at the front of what would be the magazine tube, if the M3P wasn't box fed. The Benelli M3 is basically a tube-fed "copy" of the Beretta M3. Hope this helps.
