Well, I have a 590A1 with Ghost Ring sites that I bought several months ago. I really love it. It is light and easy handling. Great fun to shoot and looks mean.
Given the above, I actually just bought a Remington Marine Magnum. Man, the finish on it is beautiful. I was suprised at how smooth the action was compared to my 590A1.
I can't wait to try out the Marine, it just feels good.
So, basically I love BOTH my 590A1 and Marine magnum
