I like mine
I have owned my 605 Poly since last July. Guessing probably somewhere between 600 and 800 rounds through it. Mix of .38, .38+P, and .357.The 3 finger grip is much nicer for the latter. I had one problem early on. It would not cock for single action. I'm not a gunsmith but I took the grip off to see what I could see and it appeared that a piece of rubber from the grip was blocking it. Cleaned it out and have never had another problem.
Working at distances of 12-15 feet in single action it's very accurate in my experience. Given that this is the range I bought it for, I don't have any complaints. Nothing to compare the trigger pull to but I'm having to work on the double action pull. Dry fire and GripMaster are helping.
Holsters are a bit tricky as the size is not exactly that of the steel 605. I use a Galco Ultra Conceal in a J frame size and it works fine, though a S&W would probably sit further down in it. Picked up a paddle holster from Wild Bill's Holsters in size for the Ruger SP101 and fits it perfectly. Also tried some holsters for K and L frame S&Ws and they fit nicely.
Biggest issue I've had is the Taurus bad mouthers, but as long as it goes bang when it needs to and is reasonably accurate, I'm not sure the BG is really going to care what shot him. If I'd had an unlimited amount to spend and a wife that said "go for it" I'd have probably bought a S&W M&P 340, but then I'd have had to cough up another $500.
So, for what I paid and how it's performed, I'm perfectly pleased with mine. Down the road, maybe a Ruger AND a S&W!.
