Hi R9:
Boards like this sell guns.
We also serve as a customer service resource. As well as a free focus group for the manufacturer.
For a company like Rohrbaugh, which is new (in that it only recently started shipping guns) our impressions of the firearm, especially since it is very expensive, will be very, very persuasive to prospective customers. Unlike the marketing efforts of a company--we are real, normal people who have no financial interest in the company, and spent alot of our own money on an unproven firearm.
