Yes that is true. Speer makes a short barrel load for the .357 now. But in most situations .357 out of snub translates into a lot of recoil and muzzle flash. You do pick up some velocity but personally I would stick with .38 +P. The other benefit of .38 are the cases are shorter and easier to extract.
I have a Taurus 85CH and a S&W Model 13. I like the 13 and am thinking about carrying that instead of the Taurus. But the Model 13 barrel is an inch longer, heavy barrel and you can notice the weight difference.
It is a .357, but I agree the recoil and especially the muzzle flash is intense! Either one will be loaded with .38 Special +P.
