Paging Rampy! 32 Magnum questions.

Since you're our resident H&R 32 magnum expert, I have some questions. My thumb joint arthritis is not getting any better. While I can still handle full power 38spl;, it's no longer fun. I know you've recently switched to the 32 and would like to hear your experiences, opinions and recommendations. What have you learned of it's effectiveness against actual bad guys? What non boutique ammo would you recommend? Anything else that would be useful for me to know in making a decision on whether to switch.

Thanks brother!
