I was considering picking up a 327 FM but, when I look it up on the various revolver manufacturers' websites it appears the cartridge is about to go the way of the dodo bird. S&W catalogs only a single revolver for it - a 6-shot Jframe w/ a 3" barrel. Ruger also has but one offering. Curiously, it's a full-size GP100, rather than an SP101. Taurus offers nothing at all. So what's the deal? Is this round DOA?
