I'm 74 and my eyes are not very good anymore. I shoot several pistols with fiber optic and some with red dots. I really like fiber optic front and rear for a holstered pistol when mowing pastures to shoot gophers. My 41 has integral front sights on both barrels so I'm looking for a solution. Does anyone make a barrel with a removable front sight and if so, what manufacturer makes a compatable high vis sight set. I have a Burris Fast Fire that would fit on the scope rail but then it will not fit in the holster. Thank you in advance.
