Texas FFL contacts your Hoosier FFL, FFL sent, Fedex delivers from Fort Worth to Fort Wayne, you fill out 4473, do NICS, take pistol home and then put photo on INGO.
This is correct, let me expand.
You can pay for it at the store, but then they'll ship it to IN. You will not be able to pay and carry it out (in your example)
Sounds like I would also have to pay shipping and an Indiana FFL fee which is around $40. So if I did it would likely end up costing me close to $80 just to get it into my possession.
If you buy the gun from a gun store in Texas, I would not expect the transfer fee to be too bad, but if you transfer it through a Texas FFL from who you did NOT buy the gun, I would expect to pay $40 or more. This is based on my experience in receiving handguns from out of state, where the receiving FFL/gun store was not making any money off the gun itself. All the established stores seemed to regard accepting a transfer as a nuisance and wanted to be paid accordingly.
Now, I did find a couple places that would do it for $20, they were not typical brick-and-mortar gun shops, they were FFLs working out of their houses or rented office space, usually one-man shows, happy for any business.
So, if you are going to buy from a store in Texas, you are probably OK on the transfer fee (might call ahead and check), but if you have plans to buy one from a friend and ship it through a local FFL, have the friend shop around a bit. Gunbroker lets you shop for an FFL by zip code, and that's how I found the one I used (Wetmore Shooting in San Antonio).
I am really just kinda trying to keep an eye out and see what I can find. The only reason Im thinking Texas is because I have a trip coming up and last time I was down the local gun shops had some pretty sweet deals.
