I bought a 605 smooth hammer .357mag a couple months ago. I was shooting with a friend out behind the house yesterday. I had just shot 10 rounds of .38 through it and then loaded it with .357 and gave it to my buddy. It FTF on the third round. Cylinder would not release. Trigger would not pull back the hammer. I took it apart and got it working again. Fired a cyclinder full of .38's have not tried .357's again. I think I'm going to get rid of it now.
