You can carry AND practice with full power .357 loads if that suits your fancy. BUT to me, shooting full power 357s in a relatively light weight M19 OR similar revolver is just not fun and probably not conducive to developing good shooting habits...I don't own a 19 but I do own and shoot a 4" Ruger Security Six and 2 3/4" Speed Six which are similar in size and even though the Rugers are recommended for full power loads I don't shoot them.
There is something real irritating about shooting full power 357s in light revolvers with short barrels and I find .44 mags and heavy .45 Colt reloads a lot more pleasant and more controllable....part of this is the heavier weight of the latter handguns but also the 357 cartridge is somewhat over-bore capacity and that constricted bore seems to magnify blast and noise. It's not the recoil that is irritating to me. This is all subjective but the bigger bores seem to have a "drain pipe" effect that lessons blast and noise. If you ever shot a full power 357 load in a short (4" or under) without hearing protection you know what I mean
For my Ruger DAs, I load a heavy Keith style SWC in front of a medium dose of Unique for about a Plus-P .38 equivalent. But non-reloaders don't have that option.
