Wanting to purchase 4510 Judge 6.5"

I was surprised this exists. It looks awkward to say the least.

For a whole slew of reasons, I don't think you'll see any increased power from it. The only positive I see is increased sight radius.

That said... this is the United States... go to your favorite shop, slap some Franklins down and ask them to order you one.

Does some manufacturer actually make one with a 6.5” barrel? I’ve never seen or heard of it other than the pic Nullcone just posted.

People have been having difficulty finding stores that stock a wide assortment of Taurus guns, but I get the impression it's a production issue, not the stores' fault, generally speaking. Popular selling models always seem to be in stock, but less popular models, like the one you're looking at, can be few and far between. I'm guessing gunbroker is going to be your best bet, where small shops can list their (sometimes) more esoteric inventory. Good luck in your search, and enjoy your new gun if you find it.

I have to admit, I found it hard to believe the Taurus website and had to "trust, but verify".

Here's a blued one for sale:

In general, the shorter the rifled barrel, the better the pattern. I don't think you're going to gain much velocity with 3" more barrel to make up for the pattern loss.

They are out of stock right now, but you can be notified when they are available, and they were asking $450 with free shipping the last time they were in stock...
