I don't have one, but I think they are on the same frame size as the 12 gauge is. The breach diameter is probably the same so I would say there is plenty of metal to drill and tap. You will probably need two taps, one a plug tap and one a bottom tap. They may be hard to find, they need to be 6-48 NS, if you cannot find a bottom tap you can probably just use a regular tap to get the holes started and then grind off some of the end to finish the threads off to the bottom. Remember you really only need 3 or 4 full threads to get the maximum strength out of the screws, so the tapped part of the holes does not need to be as deep as one would think. Not that I would recommend it, but I once had an H&R barrel that someone had drilled clear through into the chamber. They had just filled it with a screw in it and it shot fine, didn't even hurt the cases. Probably not a recommended thing but it still worked fine. Good luck. Larry
