Taurus 445 (.44 Special 5-shot) Ultralite. The way people describe S&W quality control now I would be willing to roll dice with a Taurus. Twenty two ounces is about right weight for gun so chambered.
Some years back S&W Performance Center produced small run of short-balleled .45 Colt and .45ACP defense revolvers. It had light Sc alloy frame and stainless cylinder, but used sample will cost well over $1000.
Both Taurus and Ruger offer small short-barreled revolvers in 9mm Luger. Federal and Speer made special short-barreled ammo designed to be used in guns like this. Performance is basically equal to short-barreled .357 Magnum.
