Soo.. I'm looking to join the gun crew... and to start things off I'm looking at 870's. On Remington's website it has 3 different 870's I'm interested in...

Express Synthetic 18"
Express Synthetic 18" 7-round
870 TAC

Now the website says that the regular "The Model 870™ Express® is intended for personal use and will not accept law enforcement accessories." While it doesn't have the same note for the 7-rounder. And, obviously the TAC would be able to accept accesories. So, basically, the regular 870 express 18" can't add a tac light or folding stock or anything but the 7-rounder can? I just want to make sure.

Also whats the difference between the ES 18" 7-round and the 870 TAC? Both are accessory-acceptable, right? What's better about the TAC?

I'd like a 18" barrel shotgun where I could add a folding stock, a light, or a pistol grip if I wanted. If I could go cheaper, that would be nice too.

Sorry, I'm a noob to buying guns.
