http://www.gunandgame.com they have numerous differn't sections including a handgun board and manafactures boards. Good people.

http://www.glocktalk.com though the board is a Glock board, there is a non-glock section and lot's of valuable information.

http://www.xdtalk.com a good board for XD pistols. I have a XD9 and love it, good gun.
