“When customers ask me to choose between the Mossberg 500 and the Remington 870, I go with the Remington.”
I personally prefer the Mossy 500, not for any reason in particular, just my personal preference. I find people often prefer firearms that they had experience with or good memories of, myself included.
Doing a google search for “Mossberg 500 vs. Remington 870″ turns up over 13,000 pages!
