I am kicking the idea of getting another 45. I currently have my 1911 clone and I love it, its always been a reliable accurate firearm. Now what I would like is a doublestack, single/double action trigger, decocker, and a smallish frame, and preferably a metal frame and exposed hammer. Is there anything like that that doesn't cost an arm and a leg? I know that the Sig would fit my bill perfectly but they aren't cheap. I'm hoping to get something in the 400-500 dollar range (a little above is okay). I like the XD45 of course except that it doesn't have the single/double or metal frame. Any suggestions?
