I've been thru a lot with my 605
The 605 was the first gun I purchased. I thought it would be a good size for either home defense, or later on if I wanted to conceal carry. It is accurate beyond 20ft, so it fits the bill there no problem. I have the regular hammer stainless model, non ported, flat finish. I didn't care for the boot grip, so I ordered the taurus combat grip direct from miami. I may put the boot back on for carry, but right now the combat grip is far superior to it, and I recommend you go that way. It's cheap and also covers the back of the grip. This is important if you're going to shoot magnums. I don't like shooting magnums out of this gun . They beat up your hand too much and make lots of noise. Hand held flame thrower comes to mind. Easy to clean as well with a good trigger pull.
Now, problems. Light strikes became a problem for me with this gun after about 600 rounds. I went back to the shop where I purchased it. The smith is authorized to do warranty work for taurus. He told me taurus uses a very light hammer spring to get that sweet trigger pull. He removed the 8lb spring, and installed a standard 12lb spring. Not one light strike since with nice deep dimples on all types of ammo. If you experience this, don't get upset, just change the spring. Cylinder binding has been a problem with cheap dirty target ammo after about 30 rounds, but not quality ammo. You need to keep this gun clean.
Ammo: I've tried 11 different types of defense ammo in this gun for accuracy, recoil, and reliability. I shoot 38's, so a lot of stuff happens in the chamber before it reaches the forcing cone. Long slugs work better than short ones. For instance the Winchester super x hollowpoints wouldn't shoot worth a darn, whereas the PMC Starfire Eldorado seems to work the best(nice long slug and soft recoil) I'm sure the Remington gold sabres would do well also. Winchester White box works best for target ammo. 130 grain works best. The heavier slugs kick more, and are hard on the hand.
To sum up, even with all the teething troubles, I would buy it again in a heart beat. The fit and finish is very good and very smooth. And it's a beautiful gun to look at.
