Guns, Dogs and Blades QnA

B-i-n-g-o said
Need advice...my background...have an HK 9mm, no optics. No rifles. Just got a Beretta A300 Ultima Patrol 12 gauge for HD, but I want to practice, be GOOD at it. Going to be using Federal LE 8 pellet 00 buck...does a red dot help me any, or not enough? If so, recommendations? I'm leaning toward a Holosun, if I do get one.
Thanks!

Personal preference

Shotgun is an area weapon... and does not need to be discharged at the shoulder necessarily. If i were to mount something it would be visible laser or maybe a flashlight. Those work both ways though
