I recently put an aftermarket barrel from Brownell's (Olympic Arms, I think) into an Inglis BHP; it was a nice snug drop-in that worked fine from the first shot. It wore into the lug and slide just a bit and I am very happy with it. Feeding with both factory and handloaded JHPs was also fine. I was concerned because pre-1950 Browning HP type guns had a slightly different dimensioned cross lug--but all went well.
Brownell's price was reasonable, too.
