I have both a Remington 870 Marine magnum and a Mossberg 590 [not the A1] . If I would reach out for one it would not matter which one I grabbed , they both work great . I do think the Mossberg kicks less than the Remington , if that is a concern . I replaced the safety button on the 590 with a metal one [just because everybody gripes about them] , but I have never had a problem with the plastic button on my 835 Turkey gun . The stock is about 1 inch longer on the 590 if that makes a difference [I shortened mine 1 1/2"]. Good luck , Mike...
I should add that Remington no longer does in house service , I found this out the hardway with a new Police Magnum I bought this spring . It made 3 trips back [twice they sent it to a gun shop to be repaired and the owner E-Mailed me saying he could not fix it] before they finally refunded my money .
