I keep an auto as my home defence gun, It is a Ted Williams 300 (same as Win 1400) I used it as a hunting gun since I was a kid.
100% reliable. 100's and 100's of shells, heavy, light no diffrence.
When I retired it from hunting, I cut back the brl. to 18 inches and it still patterns OO buck under 1 foot at 15-20 foot range.
The only down side is the 2+1 capacity.
I just practice "fire one load one"
