Re: Best Shotgun for $$, 18-20", Parkerized-20or 12?
+1^^
Viav13 pretty much hit the nail on the head.
To add to that, I have felt that as of late folks are making the shotgun platform entirely too complicated.
1) <span style="text-decoration: underline">Don't buy more chamber than what you need</span>. So many buy the 3.5" chamber so "they have that option", but never use it. While i've always likened it to using a .308 in a 30-06, it certainly won't improve patterns/accuracy, and you're just increasing your pump stroke....and you paid more to do so. And while 2 3/4" only is no longer seen, it's enough to get most jobs done.
2) Avoid the urge to be "tacticool". While I love my Beneilli M1 pistol grip, it certainly does not have the versitility of my plain jane 870P. I love the pistol grip for defense, but my 2 workhorse shotguns have a standard stock. Keep it simple. Adding lights, side saddles, mag extensions, pistol grips should be done as needed. While my Benelli M4 is a bad mofo, it rarely sees any use because it's heavy, expensive, unnecessary. It's the sledgehammer when all you need is a 16oz claw.
3) 12ga!!! More options, more loads. While some insist on the 20ga for "less recoil", but I have to admit that coupled with a lighter shotgun, I have yet to notice any difference in felt recoil. However, you will notice the decrease in range, pattern and power.
4) Mossberg/Remy. Ford/Chevy, Coke/Pepsi, Case/Deere. No wrong answer handle them both. Decide for yourself. However, if you can afford the Benelli...buy it
