I'm trying to decide on the Supernova, or a Remington 870. I've heard that the Remington Express models have several small parts made by MIM, and was wondering if Benelli uses MIM parts as well? This will be for a duty gun that will be shot with OO Buck and slugs exclusively, so I'm looking for a gun that will take the abuse of those rounds the best.

Sonyman - I like the sling you have on your tactical model. Could you tell me who makes it or where you got it? Also, was the 4 round side saddle hard to put on?
