Oh, of course. My pleasure. ER Shaw are typically very good barrels...many times they will shoot better than factory. That said, they are production class barrels. McGowan is in the top tier alongside Shilen, Douglas, Bartlien, Brux, etc., & etc., & so on. People typically have their favorite flavor however, my opinion is one these top tier can be chosen at random, from a hat, and produce an exceptional shooter.
