Damn good site. Prior to finding it, 95% of my time was spent at Glocktalk. I will be spending less time there now, and more here.
Big problem at a lot of gun websites is that folks get to bashing other folks for their choices in weaponry. The AR forums are the absolute worst-- if you don't have the highest dollar platform, then you are simply trash in the eyes of more than a few. Not sure but if a lot of those guys don't spend 100% of their time and money on the platform build, and never actually shoot the darn weapon. The 1911 forums-- not as bad. There seems to be, in my opinion, some jealousy from the XD community toward the Glock community, resulting in some one-way gratuitous bashing on a regular basis. In general, Glock guys like Glocks, Sig guys like Sigs, and HK guys look down their noses at both. None of them give the XD guys a second thought, probably since the LE community has largely shut out the XD in favor of Glock, Sig, HK, and more recently, S&W M&P. Beretta fanatics seem to raise the ire of the 1911 community, probably because there are a lot of ex-military guys (me bein' one) who still feel betrayed by the change to the Beretta. Most of us would rather have a sister in a brothel than a brother with a Beretta (I tried anger management counseling, but no joy).
The tactical shotgun community pretty much revolves around the Rem 870s, the Mossie 500/590s, with some attention to the Benellis and the FNs. Winchester, maybe a little.... I have detected little animosity 870 and the 500/590 camps, simply because there is mutual respect for both shotguns in the community.
My two cents....

Glocktalk has a nice little tactical shotgun forum, and the Mossberg, Remington, and Benelli camps keep it pretty civil.
