HR:
Congratulations on your decision to obtain a Rohrbaugh R9. Prepare to be amazed.
With regard to the finish of the so-called "Covert" model, I have an IMI Timber Wolf pump carbine (.357 Mag.) with Wilson ARMOR-TUFF ® Protective Firearms Finish in OD green and black. The finish has proven to be very durable and shows no signs of wear after three years of use. Of course, experience with the finish of a carbine that is used only occasionally does not necessarily apply to the finish of a pocket pistol that is carried every day. Even so, the Wilson finish seems to live up to its billing. Also, if it were to begin showing signs of wear, the finish could always be reapplied by an authorized technician.
