Yes you did, albeit a little late. I have an 1187 that I use mainly for waterfowl and the odd pasture clay. It has been good to me but I'm not sure if I'd buy one for skeet purposes.
gunsaholic might have added a couple other points too. So I'll add my .02 as the penny is soon to be gone.
Did you buy this gun as a dedicated skeet gun or was this for double duty ?
You know Waterfowling and some skeet time in the off season of Waterfowling?
If so, you did well enough, providing the gun fits and the balance is there for you.
Price comes into play as well, but it appears you have over come that hurdle. Go price any "B" gun and your wallet will feel heavier (for now).
If I researched it correctly the 11-87 is a variant of the 1100 that served Remington well for 40 years.
It appears to be relatively easy to clean and maintain, the trigger groups pops out by removing a couple of pins, the bolt slides forward along with the action bar assembly (I might be describing it incorrectly) but before this step there is a veton o-ring and the piston seal assembly have to be removed.There is a particular order to which they are installed and once you have done it a couple of times it is a no brainer.
Type in Remington 1100 gas piston assembly in google and look for the Brownells link, there is a video demo of the take down and install of those parts.
Should the gun have issues with light loads the a fore mentioned maintenance should lead you in the right direction for correcting the issue.
Should the 11-87 cause you to break constant 50's at the skeet field I would suggest you take up another sport as the guys with the "B"guns will start to hate you , especially if you ask"if this is Remington Country" or buy one of those "B" guns so you can hang with those less fortunate guys.
Seriously, the 11-87 will serve you well both on the Skeet field and in the blind or jump shooting roosters.
Enjoy your new gun and post up some pics of it in action!
Tight Patterns,
