You can fill in the gas escape slots on the 1100 fore end and direct the gas out the front of the fore end by drilling hole in it. I did this on several 1100's with fair results. Most, but not all the gas was directed out the front of the gun. You do need to make sure you don't extend your hand too far. The gas is hot, but wont burn you. It will scare the heck out of you.
