So I've decided that I'd like to purchase a shotgun for home defense and after doing some research online and in store I've narrowed my choices down to two models and would like any feedback, positive and negative, regarding them. Currently, I'm leaning towards the Mossberg 930 SPX, but also heavily considering the Remington 870 Express Tactical. Now I know they're two totally different beasts, one being pump action and the other semi-auto which leads me to my first concern. Pump actions, from what I've gathered, are far more reliable in regards to jamming whereas semi-autos can jam more easily. Also, there is something quite foreboding in the sound a pump action shotgun makes when you chamber a round and that in itself could make a burglar run. On the other hand, I like having the ability to squeeze off as many rounds as my finger can squeeze off. The price difference between the two isn't so drastic as to dissuade me from purchasing the 930 so cost isn't an issue. So, I put it out to you the forum. What are your thoughts? Thanks in advance for your responses.
