Love the .32 calibers for revolvers.
I own two Taurus 327s, a Ruger GP-100, and a 3 inch barrel SP-101 in .327 Federal.
Also own several H&R and NEF .32 H&R magnum revolvers.
These guns compliment each other and the versatility of the .32s is a good selling point.
Need something that has some power for defense, but kicks less than a .357 magnum?
The .327 Federal can do that.
Need a slightly less powerful rounds for general purpose use,fun gun, defense for a recoil sensitive shooter,teach a new shooter? The .32 H&R magnum can do those. 85gr.-100gr. rounds to choose from. Not a powerhouse, but still has to be respected for what it can do.
Need something even less powered that is fun to shoot, user friendly, and a good teaching gun/caliber combo? The .32 S&W Long gets the nod.

These are good links to use to find ammo for these calibers.
Even
www.buffalobore.com has come out with .32 H&R magnum and .327 Federal magnum defense rounds. If the market wasn't there they wouldn't have bothered making ammo for the two calibers.
