Since there's no shotgun forum.....
I saw in the CDNN catalog that they have FN 12ga pump guns with 8rnd mags and 18" barrels for $299. From my research this is a pretty good price for a pump 'tactical' shotgun.
But I haven't heard much about FN shotguns.
So edjimicate me, should I look for one of these locally or go with something like a Remmington 870 tactical model or a Mossberg 500 tactical? IIRC the Mossberg 500s that are "tactical" are 6 shot for an 18" bbl or 8 shot for a 20" bbl, which means you trade capacity for weight and bulkyness. I also know that there's billions uppon billions of accessories for the Remmington and Mossberg shotguns, and I'm not sure if the FN ones are similar enough to use those or if I'd have to scour the EE various places to find one.
Of course, lacking the money to make a purchase right now makes this all an excercise in learning more than anything, I wish I had $300-500 burning a hole in my pocket. Oh, and I'm not planning on using a shotgun for hunting birds so the shorter the barrel the better, and double barrels are about 5 times my theoretical budget. I'm thinking more along the lines of 3gun matches and possibly elk/deer hunting but most likely just 3gun and blasting at the monthly shoots.
