So, at my local shop looking for a shotgun:
870 Express...stock felt small and fragile, like it would easily break. Not saying it would break, but to ME it felt like it would. And for the life of me, I could NOT shoulder the 870 with any degree of comfort. Reach was far to long, my left arm was straight to get the forestock. Racking a new 870 was not a pleasurable experience but I do understand that this would break in. Aftermarket up the ying yang which is good. A quick fit and finish review seemed fair.
887 Tactical...Picked it up, and it just felt 'right' Sighting was easy, shouldering was a breeze and felt good, action felt better (but it was new and like the 870 would change) Left arm reach was WAY more comfortable AND natural. Very limited (read...almost none) aftermarket, but what do you really need that this doesn't already have? Again, quick fit and finish seemed fair, although the coating seemed to be even without any problems.
Both were (are) comparable in price. But for me, I am going back tomorrow and taking another look at that 887, and more than likely, if I don't get the 887 tomorrow, it will be in the near future.
