I own a 590A1 and i like it because it has a screw cap and it is very easy to replace the magazine spring. I believe the 590 is similar without the heavy barrel.
My first shotgun is a Maverick 88 which is similar the 500 except it has a trigger safety instead of a tang safety. I under load by one shell since I don't want to deal with replacing the magazine spring. To replace the magazine spring I need to remove the magazine tube.
