Although your preference is for an "all metal" pistol, I'd really suggest that you try an M&P40. It is the softest shooting .40cal pistol I've ever owned (and that includes the snappy (but accurate) G35, the horribly inaccurate Vertec 96, the way-too-heavy Baby Eagle .40 and the ancient Browning HP and others. It's very accurate right OOTB with a very decent trigger. Don't be fooled by the feel of the trigger at the gun counter.....you have to shoot the M&P to appreciate how nice it is. The interchangeable back straps allow you to "tailor" the grip to your own preference.
Many "all metal" pistols have plastic grips ya know.
