Ramon,
There are a few pluses and minuses on porting which I'll let the other more qualified people on here comment about. There are also lengthy discussions on this forum about it. However, the felt recoil is the one pluses that was too much to be ignored for me. Relatively cheap at $85, tamed it quite a bit, along with the magazine extensions. I have two handguns that have been ported now, one fully compensated 1911 and an assortment of rifles with a variety of compensator's and flash suppressors. Bottom line is they work.
