I have one in 44 mag that I bought new about 36 years ago. It had the 6" ported barrel and the unported barrel. The basic gun has never had a problem at all. Shooting with the ported barrel has had some problems because the barrel ports vent some copper that builds up between the barrel and shroud and makes it hard to get apart. If you shot too much they may be welded together. I can't tell any dfference in recoil so I just retired the ported barrel.
