Go to the previous link and contact any of the customer service #'s provided to Ruger firearms. I had a conversation with Ruger's head armorer on Friday. He says that Ruger has developed a PC-45 carbine at the AZ plant. It has cleared R&D testing and from what I hear it will accept 1911 mags as well as P-90 mags. It also feeds all hollowpoints and can handle +p unlike the Marlin Camp Carbine of old. The problem is, Ruger brass thinks that the public won't buy it if it is added to their line. I was told that unless the public responds, the carbine will be shelved or sold to LE Depts. only to recoup prototype and R&D costs. If you ant to get this ball rolling and "light a fire" to make the Ruger brass reconsider, help me flood the customer service depts. in AZ, NH, and Connecticut with phone calls and e-mails. I have provided the previous link to the only #'s I have and I will try for the e-mail links immediately.
I've been told by guys in Ruger R&D that this carbine is the real deal, better than the PC-9 and PC-40.
Thanks guys, I'll find some more links...
