Name of the shotgun and link to purchase it?
That pictured is the Mossberg 500/590-12 Gauge Pistol Grip.
I used it more for an illustration/example than anything.
I pulled the image from...here...not from a dealer site.
Here is the 500 Cruiser - 20 Gauge, 6-Shot, 18.5" Barrel, Pistol Grip Stock, Bead Sight
...from Mossberg's own site.
MSRP: $447.00
