I also recommend the Remington 870 Tactical. I would like to get a field barrel for mine as well, with the tactical barrel/choke on it it is great even at moderate distances (50 yards).

Everyday carry? full dress is a Kimber Tactical Ultra in a Galco Kingtuk (very similar to the Crossbreed shown above) when I want to conceal or a Galco Paddlelite for open carry. Summer carry is a Ruger LC9 in a cheap Uncle Mike's IWB beltclip holster until I find a better holster for it (not a lot of options yet). The LC9 is nice - not much bigger than the LCP but uses 9mm instead of .380. I also have a Ruger LCR .357 waiting for a decent ankle holster as a BUG.
