My sister in law and her momma use 410 mossberg 500’s with 18 inch barrel and pistol grips. Actually one’s got a barrel that’s a rail and was once longer and cut down to around 19.5 inches. They paid around $275-350 each, one was used and one was new. Very manageable for her mom, whose 75 years old, and she’s a wicked shot with it eliminating all the squirrels in her neighborhood
