Adjustment would be tedious and it would not look all that attractive...but it would work.
i have used this mod for several yrs, works great.
if u have a thin guard take a small piece of aluminum or steel and file it to fit behind the trigger and use a bit of JB WELD to hold it in place. after it dries it can be sanded or filed to clean up and a bit of black paint will hide it. or if u wish to get picky and want it to match your blueing a bit of glossy dark blue paint and add black to it till u get the right shade or at least close to it and almost custom.
