Got a call today from a FFL friend letting me know She has a 4" for sale, did not get -# and have not seen the girl in a while, but She has always shot me straight (pardon the pun), asking price is around $500, She'll work with you, I really can't say enough about her.
If intereted call Carmin @ 423-336-2675, if you are interested in a picture let me or her know and i can schedule a service run in that area and would be glad to help your and her out.
Now, before anyone gets excited this is Fugate's Firearms in Charleston TN, not the outfit that seems to get everyones ire around here, I've never dealt with them but have bought dozens of fine revolvers from Carmin. Check her out and tell her 'Russ the phoneguy told me to call you.'
Good luck!
