Maverick 88 20 Gauge shotgun.
It’s made by Mossberg, but assembled in Mexico instead of the US like the Mossy 500 and costs less.
About $200.00 for brand new if you can find one as nearly every source I checked says “Out of Stock”
12 Gauge is about the same price, but again, “Out of Stock” in most cases.
Academy Sports, a chain of Sporting Goods stores in the SouthWest US has the Maverick 88 in 12 and 20 Gauge listed for $179.00 as well as a “Youth Model” in both 12 Gauge and 20 Gauge which might be easier for an older person to handle.
Inexpensive and basically a re-branded Mossberg 500.
In fact, they are now called a “Mossberg - Maverick 88”
Best value for a Shotgun IMO
And yes, at combat range (7 yards or less) the shot spread will only be about 5” in diameter.
The myth of point and shoot and you’ll hit your target is just that — a myth.
