Looks like Remington didn't do their homework, leg work, R&D, etc. to get this 9mm pistol off the drawing board, into production and make it successful. I guess they got lucky on the Remington 1911 .45 pistol. But then there isn't too much to screw up on with a John Browning designed handgun that has been in production for over 100+ years.
