I'm sure it's 'enough', but...
For a while my CC gun was a 5 shot SP101 357. 38's were fine but I soon discovered full 357's were enough of a handful that accurate follow up shots just took too long. After chewing on this issue for a couple months, I sold it and picked up a Kahr K9. 8+1, takes +p ammo.
On a side note I discovered the 3" version I had was the same exact size as my Sig 220.
