I have one, myself. It's a very nice gun. The trigger could use some work, but it's certainly normal for Ruger triggers. I've had a few problems with extracting .32 H&R cases from mine. The chambers are loose enough that, when the spent case gets most of the way out, it may slip around the extractor claw. This isn't a huge hairy deal, as I'm quite fine shooting the full-power .327s.
I was handloading for .32 H&R before I bought this thing, so it just required me to move my dies out a little. It leaves a little bit of bulge near the head of the case, but since that bulge came out of my chamber, it goes back in without an issue, too.
Ammunition is plenty available in my area. There's a store that, if I didn't handload almost exclusively, I could count on to have the Federal American Eagle 50 rd boxes. I think I saw that brass is available, now, too.
It's not your father's .32
