I have 4, and owned a fifth, 3 Single7's and a 4 inch Sp101 currently. I had a Blackhawk 8 shooter, but that was much too much iron for such a small caliber. I cannot agree with Outpost on this one. My 30. Carbine Blackhawk was not at all in the same class as my 7 1/2 inch Single Seven. Not even close. My 327 Single 7 7 1/2" is the only revolver that I have managed to shoot a 1" group with in this century (more my fault than the gun's, I fear). I never managed that with the carbine Blackhawk and my eyes were younger back then.
They are noisy. A full on 327 is LOUD. But then, so was the 30 carbine Blackhawk. What I like is that you get bottom end 357 ballistics in a smaller lighter gun. The 4 inch sp101 is a pretty nifty package, though only after you perform a serious action job. Stock SP's come with gritty heavy triggers and the 327's are no exception. I tried for years to get a 3 inch when I was still back in California, but it never happened. I think that would be a great CCW revolver, but I finally decided you can't own 'em all, so I gave up on that particular unicorn.
Bottom line is that I am a fan. I keep toying with the idea of getting an H&R and making a single shot 327 carbine, but I am getting older and find it increasingly hard to justify new toys when I don't play with the ones I have. But a 327 640 S&W??? Hmm, that might follow me home..
