Interesting rail...something different I guess.
Just some suggestions....I noticed that you don't have the barrel clamp on with the magazine extension. An extension (especially a 3+ shot) risks being sheared off the mag tube threads if you bump it against something and not have the clamp on.
You should also look into replacing the carrier dog spring with the heavy/black/1100 version as used on Police models. If you want, you can also replace the extractor with the tool steel version also used on Police models (though 870 extractors are not known for breaking).
How about an over-sized safety so that it can still be easily manipulated with that pistol grip setup?
