Now if the Muppy had the same size grip as the 311, but yes, in Mudders, it would be perfect! Hum.... wonder how much of the Muppy grip you could cut off before you got to steel? If you didn't mind any steel showing, you could even cut it off to your desired length and re drill for the rivet hole. Shame I don't have a spare Muppy, It might be interesting.
