Good for what?
Plinking? SD? HD? Weighing down a purse? Target practice? Stopping rampaging whitetails?
I have owned the Blackhawk, GP-100, SP-101, and LCR in .327 Federal.
Keep in mind that they all have heavier than usual springs, in order to set off the *rifle* primers used for the cartridge. And most people that try reducing spring weight, or installing lighter springs (even the 'standard' springs for .38/.357) end up with light-strike issues.
The GP is great. (But I sold mine.)
The SP has a notably heavier trigger pull, but carries better. This is my "compact" woods gun.
The Blackhawk is a heavy chunk of steel. Same size as it would be if chambered in .45 Colt, but with smaller chambers and a smaller bore diameter. Fun for targets and plinking. No good for any sort of carry.
The LCR is my primary carry gun. But, having a fondness for what is left of my hearing, I will not shoot it (or any of the others) without hearing protection. I carry the LCR with .32 H&R in the chamber. I can, surprisingly for the terrible "sights", shoot it very well to 100+ yards. But it wasn't made for that.
