Just to update this post: I have had this 605 for a little more than a year and it has been flawless. I have about 2k rounds through her now, and lately I have been shooting mostly 357 ammo. I load some 158 sjhp's at 1150 fps for practice. I haven't settled on a carry round yet, but I am leaning toward the Barnes 125 gr TAC XPD. They shoot pretty good through this gun, but are just a touch on the snappy side. I have shot several hundred of the Reminton GS 125 gr BJHP's, but I am a little concerned with the jacket seperation in ballistic gelatin. It's a shame because the ammo shoots really well in this gun. I tried the Speer SB gold dots, but they are a little tame. I might roll my own with Winchester 125 gr sjhp at around 1200 fps.
