My wife carries a titanium S&W in 32 H&R magnum. She easily shoots it. 6 shots of 98 gr. HP going 1000 FPS is pretty decent protection. Continuing my .312 trend, I just bought her a S&W Shield Plus in 30 Super Carry. These little guns are selling for $299, which is a smoking deal, and the cartridge really has a lot to offer.
The 30 SC is based on the 327 Magnum, from what I've read. I think these rounds, just slightly less powerful than their counterparts (32 mag to 38 spl, 327 to 357, 30 SC to 9mm), have much to offer recoil sensitive shooters. Hell, I'd carry the Shield+ in 30 SC in a heart beat. It's just barely shy of 9mm ballistics and carries a couple extra rounds. It actually out penetrates 9mm in the popular defensive loadings by an inch and, as we know, putting a decent slug into the vitals is what stops a fight. In a revolver, being able to go from 32 SW Long to HR Mag up to the 327 magnum makes one helluva versatile sidearm, from the field to the streets! I believe there's plenty of room for the 32s, just as there has been for the last 150 years!
