It’s relatively easy to
split with the 9mm Nagler. Anyway, since transparency is not very good,
the secondary is a bit difficult to see. In fact I use averted vision at
first to observe it, but after some time, it’s easy to see the secondary
directly, although it comes and goes. Primary seems to be white-yellow.
No color perceived for the secondary. Ana calls it a “birria”, that is,
a 5 on the HS scale.
