Never had a reliability issue or short stroking an 870 while water fowling and if the gun goes submerged you just unload, empty the water out, check for bore obstructions and resume hunting. End of day remove the 2 pins for the trigger assembly and remove. Spray out the assembly with WD-40 or CLR, swab the barrel and coat the exterior with products previously mentioned. This model is easy to disassemble and maintain even in the field if you carry a multi tool and bore snake.
I HAVE short stroked a BPS 10 gauge when switching to geese, this model requires a long pull on the front end to fully eject out the bottom, pick up a new 3 1/2" shell and go boom. Several times I have heard a click when transitioning to this gun. This model is also more difficult to disassemble when adversity strikes.
