Remington 870 12ga 26" barrel. Synthetic stock. I got it, two chokes, a case for it, a case of dove and quail loads, some duck ammo, and several boxes of low-recoil 00 buck for defense for $417.10 out the door at Bass Pro. And as much as I dislike buying firearms at BPS, this one was a great experience... it was on sale, and the service wasn't nearly as bad as I'd come to expect. The guy let me fondle at least 20 different guns until I found one I liked. And I also played with a Sig compact 1911... SWEET! It's on the "gotta have it" list (right below the AR that just moved down from the "gonna buy it" list). What kind of modifications should I make to this? I'm going to order an 18" barrel soon. Are the night sights that are available a good deal? And, what do the chokes do? I've got "Full", "IC", and "EM" chokes. Which one do I use for what purpose?
