I did it for less reciprocating mass and a non-reciprocating front sight without the extremely heavy front end of a sight tracker, with the added bonus of it being an interesting design challenge. The slide on mine is 4.5 inches long so fairly light. The front sight holder is aluminum, and the entire barrel assembly (barrel, come comp adapter, front fight block, and front sight) weighs what the bull barrel weighed before we started. It is much less nose-heavy than a 6-inch sight tracker. I have since added an SV steel grip, so it is quite heavy, but it balances great and is very flat. I like it a lot and I would do very little different.
