I've got (what appears to be) a fairly pristine 4516-2 coming in today.

Next on the 3rd gen list for me will probably be a 4506-1. With the adjustable sights. And preferably the black trigger/hammer--just like Denzel had in Training Day I'd also like to get a PC Shorty 9 or Shorty 45 at some point.

I currently own a 4516-2 and I really like it. But the one I have on the way looks like it's in much better shape. So it's on the docket for "favorite" status. Currently, I have a 6904 that I've got quite a few rounds through; it has always served me well, and it's one I don't think I will ever sell. So I guess that equals "current favorite."
