Listen to lee lapins advice...
Lee said a few things throughout this thread that are worth a ton of add-ons and do-dads and do-hickeys and such for the shotgun.
1. Check out those shotguns that catch your eye. Hold them, shoulder them, "shuck" em, bring 'em to the fire position quickly, etc,,, Turn the safety on/off, IF you can SHOOT them! See, no EXPERIENCE how they feel and fit, then decide which is the best "FIT" and buy it.
2. Shoot it, shoot it more, shoot it some more after that. And when you're tired of shooting it, well shoot it just a little more.
3. Personally I like a stock SG. Nothing feels quite like a wooden stock from a trusty old Ithaca 37 or Defender 1300 coming up and tucking into the shoulder/arm in preparation for a volley. Firing the SG is the best way, the ONLY way, to become proficient and it's the best ADD ON that money can buy.
If you want to see "SLICK LOOKING" shotguns then rent an arnold movie at the red box.
