Recently, Cabelas started selling firearms (including Remington 870) online. Now Brownells sells firearms too.
Thanks to Charles for sending me link to this training document. It will be very interesting for all shotgun owners:
The key to success to competition shooter is to never stop and try new drills, different stances and of course to experiment with equipment.
Benelli Supernova is a great shotgun but it has some things which can be improved. One of such things is slippery forend. It has groves but plastic is slippery, I wish I could get Hogue overmolded forend for my Benelli Supernova, I miss it so much.
By the way, this is one of things why I love my Rem 870, you can choose from hundreds of upgrades! Accessories for other shotguns are very limited.
