I had one of the 415Ti 2.5" .41 magnums. At 21 ounces, it was feisty. The .45 ought to be perfect.
Frankly, I wasn't super impressed with the fitting and construction of the Total Ti Taurus revolver (particularly that of the star on the back of the cylinder that the hand engages to turn the cylinder), but the gun always worked fine. And, since I paid $299 for it, brand spanking new, it struck me as a good deal for a "fun gun." I hiked with it, and it was pleasant to carry. The trigger was fine but not good, and the gun was decently accurate but not especially so.
I don't know. I'm old enough experienced enough and comfortable enough now to say things like, "Gee, I really prefer things of higher quality than this." But the Taurus works. So, I guess it's one of those, "You get what you pay for," deals. Personally, I don't think Taurus revolvers are for me (after owning two of them), but if funds are limited they might be just the thing for you.
If you're looking for something that reeks of quality, though, you'll be disappointed.
Hope this was of help.
