Farmer 45,
Don't have experience with 2 port vs. 4 port, but have compared "identical" SRH 9 1/2" barrelled 44 mag revolvers. I bought both as new revolvers and had one 4 ported by Mag Nu Port with action work. I was surprised to find that while the ported revolver had noticeable reduction in barrel rise, I was not able to tell any difference in straight back recoil. Certainly a less than scientific response, but another companion shooter was of the same opinion. Their action work was moderately priced and made a very noticeable difference .... very nice work.
