Yesterday at the range I was talking to a gentleman who had brought a brace of revolvers out. Among them was a Ruger Sp101 4" in .357 mag. I had never handled one much less shot one. I thought it was a spiffy little piece but found it a little snappy, especially compared to the S&W 686 he also had. I was also struck by how the Ruger represents what Glock fans have been wanting for ages: a compact grip with a more or less full length barrel. I can't help but think however that the .327 Federal is much better suited to the SP101, get a full 6 shots and less recoil. Is this cartridge even still around? Is it impossible to find? I've heard that ballistically the .327 is similar to a +p 9mm. Is that true? Anyone out there a fan of this caliber?
