best resource for 870 express barrels??

[Averageman]

I got a great deal on a Rem 870 express Magnum I want to put a HD barrel on it, side saddle and a larger more ergonomic safety.
I dont want to go all Mall Ninja with it as this gun will be handed down or later sold. Keeping the Rem choked barrel is my intent.
Thanks all

BTW $150 for the 870, was a heck of a deal.

I just ordered an 18" barrel directly from Remington. Might want to give them a call.

I also ordered my 18.5" fixed choke barrel directly from Remington. Since some other retailers charged high shipping and even sales tax, Remington was actually the cheapest.
