I did and it was fine.
My advice is NOT to fit the silver TP, it ruins the firing cycle.
If you want to cover the PA, get another plastic trigger housing moulding that hasn't been cut out for the PA wheel, you can heat it make a "power bulge" and it will be hidden beneath. ( This was Colin Matthews idea I must add :-))
In your shoes, I would just enjoy my gun, don't worry and don't do anything to **** anyone off
