It is your pistol, do what you want.
Personally, I would leave well enough alone.
When you remove the finish from the barrel, you reduce the diameter
and create a looser barrel to slide fit, thereby reducing accuracy.
My C-100 is very accurate and I would do nothing to reduce that.
I shot one 5 shot group into 4 inches at 50 yards last week, from
a sandbag rest. The bullseye was in the center of the group. This
was my best group ever with this pistol, however it is one of the
most accurate pistols I have ever shot!
