Congrats! There is nothing wrong with a 20 gauge for HD. The recoil is manageable and the gun is very good! I would look into a shorter barrel (Remington and Mossberg both make a shorter barrel for the 870 -I bought mine at cheaperthandirt.com). I load my 12 gauge with #4 buck, but have a lot of 00 buck handy.
The barrel I got from the website is a bona-fide Remington, complete with stamp & trademark. CTD does sell some real cheap stuff, but this is brand.
