I fully dis agree with a 28 GA, they pack a punch, just less bb's
but have very close to power of a 12 ga, less recoil, lighter guns, and great for kids(adults too)
problem is more ammo related, not all places stock it
have a look at a chart that show's FPS and LBS of energy, and you can see its NO light weight on power, WAY better than a 410 and IMO< a better gun than a 20 for smaller shooters, due to most guns are lighter and again less recoil from all I have shot
carried many of them over the yrs for upland game birds across the USA
much more fun to me walking with a 5 lb gun than a 7+ lbs one ??
