With auto's, you have to find the ammo the the gun likes. I prefer to choose what I like!
12ga pumps eat what they are given, bird shot or buck, no complaints. If it short cycles, its operator malfunction!
Remington 870 or Mossberg 500, take you pick.
Mr. Piper;
Your advice is excellent.
My primary home defense weapon is the Remington Model 870 Marine Magnum. Back up is a Ruger .357 Magnum DA revolver.
