Looking for opinion and advice... I was considering buying a CZ Scorpion PCC or a Mossberg 500 20gauge but I am leaning to the new Ruger PC Carbine. My main purpose is home defense. What are the thoughts of the experts re: PCC vs shotgun and the new Ruger PCC vs the Scorpion? What accessories do you recommend (light/laser or red dot sight, any modifications)? Finally, what training would you recommend for me?
