Nope.... the trigger comes with very easy to follow installation instructions and the whole job takes about 15 minutes. Easy as pie.... If you go to Bobs website (you can find it in the "mall") I believe you can look at the installation instructions before you even buy it. It really is easy to install.
As for the best price on a CFX,,,,,, check out Midsouth, pyramydair,, or some of the other online dealers.
