i dont think its an issue of what brand it is or how its made because between me and my brother we have a couple model 5oo-s with never a problem. i bought a remington 1187 and it would hang up on ammo but my mossberg 9200 auto spits out everything form skeet to buckshot smooth without a hiccup and cost alot less. didnt leave me bitter about remington i still buy there guns its reallya matter of getting a good one.
