Assuming you mean 'Benelli' shotguns... type benelli into any search engine and you'll find their official website.
You can purchase a Benelli M4 shotgun by going to the official Benelli Shotguns website and finding your closest dealer by simply just entering your zip code.
The M1014 is the Benelli M4 Tactical. It is available only in semi auto. The Benelli M3 is the closest thing you'd find - it has the "dual action" feature, to where it could operate either in semi auto or pump action mode (in a similar manner to the Franchi SPAS 12). Additionally, Benelli has a whole line of pump action shotguns (the Nova series) which will share some commonality with the M1/M2/M3/M4 shotguns.
You can contact Benneli through their website at benelliusa.
I know this a really simple answer but take it to a gun specialist.
There are many places where one can buy a Benelli shotgun. One can purchase these shotguns from local gun stores. One may also purchase these shotguns at gun conventions. One can find gun stores in their area by visiting a directory.
What do you mean by resistant? All weapons are resistant. How much will depend on the finish.
