When I was looking for a metal framed 9mm for my gf at the time, most of the serious heavyweights I know tried to talk me in to a polymer 9mm. When I explained that wasn't possible, the two recommendations I got were overwhelmingly the Sig 226 and the BHP.
If I could have gotten Erin interested in a polymer gun I would have...but that's not what floats her boat, and I figure at least she'd shoot the gun if it were metal. She just doesn't like polymer, even though all the most reliable pistols now are polymer framed. When it comes to girls, you have to accept that they will often put aesthetics ahead of objective results, which is really the only justification left for avoiding polymer guns.
But, as I asked the guys on M4C, if you had to pick a steel framed 9mm...
If it was steel, not aluminum alloy, most of the heavyweights said BHP. If alloy was acceptable, most said SIG. But if those guys respect BHPs, then that says to me that the BHP is a respectable machine.
