You are better off getting one specifically engineered for the 500 rather than trying to make one made for the 870 work.

Consider the Hogue Tamer. Best pg I've used and considerably cheaper...if the Speedfeed model doesn't pan out.

There's a question about whether or not they actually made one for the Mossy at all, DK. They swore they did....but I've had them mail me three directly from the factory for the Mossy 500 and gotten R870 parts instead every time. They swear the parts are the same but they aren't. The R870 is clearly stamped "R870". The 870 grip is about a half an inch too narrow for the Mossy....the receiver will overhang the grip by 1/4" on both sides. The top roughly lines up with the receiver but the bottom hangs about 1/4-1/2" too low....and that low plastic, sharp edged, cuts your finger after two or three rounds. The 870 grip also has a squared off trigger guard opening that doesn't fit the round Mossy guard....and to get it to fit, you have to first start the grip bolt and then hold the grip in rough alignment as you tighten it which risks stripping the bolt hole in the receiver as you force it. The bottom edge can be smoothed with a Dremel....the other three sides are too little material already so cutting more doesn't fix them.
Bottom line? It doesn't fit. Can't be made to fit in any easy way.
Midway once sold those "Mossy" Speedfeed bird's head grips....last time I looked, they had a 17 negative rating and got dropped from the entire site. If they were still there, you could have read the feedbacks.

Why would you want to? Thats just silly. Don't crossbreed, history has shown it never turns out well. Example(tv show "swamp people")
