Kent, no Sir. Not with a stock Taurus 9mm 24/7 G2 barrel. The hood dimensions are not the same as some other pistol manufacturers.

while it may be possible I could not find anyone who has done it and it would take more than the barrel you would need recoil spring and magazines at the very least and you would have a gun that is not covered under warranty my advice is to just buy a 2nd gun in 9mm and save yourself some problems
