Where can I get a Taurus 24/7 40 cal. pistol that has a barrel of 5"? I've seen them on the Taurus website but Ive never seen them anywhere else. All I see is the 4" barrel pistols for the 24/7 at gunshows and online auctions.

I sent you an IM, here it is again -

Impactguns.com I believe has them listed.  I think that you have to do a search to find them.  You could also give them a call.  They do have some pretty good pricing.  I have also been looking for a 5" or long slide without any luck except from them.  I haven't persued them yet because I want to see it before I buy it.  Let me know if this helps.
