I own the mp-310 & I love it!
Its called the Russian tank by its owners because of its boxy shape, weight and punches whatever its aimed at like a tank! :twisted: . Its a bit on the heavy side but shoulders and swings well, every time ive pulled the trigger it doesnt go bang? It goes ""WHAM""!!!. Ive owned mine for 4 years and never any indication of a problem. very nice burl wood finish, mobile choke system, a breeze to clean. Id say I have about 1300 rounds thru mine, its my rabbit, quail gun. Another thing ive noticed with this mp-310 from other shotguns, with other guns after shooting the prey might herk & jerk, shot with the mp-310 all you see is a puff of hair or feathers and no more movement period! (Thats gr8 when it comes to quail) Dead RIGHT NOW!. I dont ever plan on selling mine, its a damn good shotgun, hope this helps.
