I am currently testing a Mossberg 935 , I have to write several reports on it over the season ( not 100% sure if I have to return it after the season )
So far after putting close to 400 rnds of 3" and 3.5" shells
I have not had 1 problem , expect for when I tryed cheap dove and trap loads
To see if they would cycle , they wouldn't most of the time
But it isn't designed to work with most 2 3/4" loads
Not sure exactly what it would cost you
But from memory it is less than a 11/87
