If you want an I frame, I would suggest a 38 Regulation Police over any 32 caliber I frame. Not powerful compared to 38 Special and larger, but at least it carries a 145 grain bullet and has some power.

For comparison - Standard Factory loads:
32 S&W ME is 97 foot-pounds
32 Long ME is 132 "
38 S&W ME is 175 "
38 Special ME is around 250 "
357 Mag ME is around 540 "
380 Auto ME is 191 "
45 Auto ME is 300-400 "
