Dberg - Welcome to the forum and thank you for your service!
While my Rohrbauh is not NP3'd, I have two other carry guns that have been treated. I highly reccomend it! I also have certain parts on other guns treated as well.
You will not be disappointed.
Again, while my Rohrbaugh is not ported, I have other carry guns ported. There are pluses and minuses.
I think it would probably be best to hear from ccoorreeyy since he has at least two of each in R9s. I think that would be a more fair assessment.
Enjoy the forum
