I've owned two "ported" S&W 357 revolvers.The 3" L-comp and a limited production 4" L-comp. In both cases the recoil wasn't reduced at all but the muzzle jump/flip was reduced. Consequently faster follow-up shots were possible.

This was accentuated by the power of the load being shot. Shooting 38 Specials, even today's so called +P loadings, there was hardly any advantage to the "comp" models. Fill the cylinder with 357 Magnums and the effect could be immediately noticed.

YMMV,
Dave
