I have a .40 BHP and love it. Yes, it is heavier than the 9. Yes, the heavier slide makes it top heavy, to a degree, but I offset that a bit with a set of Alumagrips (not intentional but it turned out that way). The extra weight soaks up the .40 recoil which makes it a joy to shoot in that caliber. I ended up with one of the later models and the trigger was so good out of the box that I did not remove the magazine safety, which I've done on all my 9mm BHPs, and the pull is just under 6# and not gritty at all. I guess I got lucky. The fact that they discontinued it means the prices will go up over time which also makes me happy. Win/win.
Fool me once, shame on you. Fool me twice, shame on me.
