What part of the state are you in?
Northeast of Baltimore up into Harford county, but I don't mind traveling a little.
While filing out paperwork on a Blackhawk I just bought, I saw that A1 had a very nice Ruger 5" or so blued blackhawk. Not sure what caliber it was as I sort of glazed over it as I dont need another but may be worth calling about.
You probably dont have time, but Warsaw arms had some incoming that if you paid for overnight you might be able to get to workout. Its a good price for a convertible stainless dealer exclusive in today's market
