I carried a Taurus 445 which is similar to a Bulldog in .44 Spl. It was ported and I love it. Carried it for about 10 years before selling it.

Flash at night is dependent on the powder used. If you get flash with one bullet try another it may be better.

Till I owned a ported revolver I didn't think much of them. When I fired it at targets my opinion changed.
