If you need to research Taurus 450s there is this for research purposes.

There is a fan club that would like the Taurus 450 to become a regular offered item again.
If you want to stay with the .44 Special then the Taurus 445 is the one to get. New ones are at the
www.gunbroker.com ,
www.gunauction.com, and at
www.gunsamerica.com , usually.
The 450 was built from 1999-2005. The UL model weighs 20 ounces. The regular model weighs 28 ounces. It's built on the Taurus compact frame.
There is also a titanium model as well. Made from 1999-2002.
100%:$425; 98%:375; 95%:$325; 90%:$275; 80%:$225; 70%:$185
ADD $31 for a UL model.
Model 450T:
100%:$500; 98%:$435; 95%:$375; 90%:$340; 85%:$275
The small number made do make it a more desirable item.
Add to that that gun prices have shot up over the last couple of years and the price might be considered a bit high even though prices have sky rocketed.
I own 7 Taurus 431 or 441s and none of them were that high in price. Close, but still lower. Granted, this is a different model and fewer 450s were made.
Here's a 445 in .44 Special for a lot less.

There is a big difference. If it is the 45 Colt cartridge you want the gun for then go for it if it fits you and your needs.
