Alan,Anschutz make a wide trigger shoe that will fit on to Morini trigger blade,I have one on a rifle,just measured it,it's 13mm wide,and increases the trigger depth by approx 3mm,it's held in place by 2 opposing Allen screws so will not damage the trigger blade,Intershoot have one in stock(Anschutz trigger shoe 5080-U1) I got mine from the NSRA shop at the Lord Roberts,they may have more in stock.
