I have had my PT 145 Pro for a month and shot everything I can get my hands on.  At 25 yd it shoots 4-5" left and 4-5" low.  Sense I would like a set of fiber optic sites I have not worked on the sites much.  I could drift the rear sight and fix the windage.   I need to file the front site , but  that would not move the dot in the sight picture.  Two thoughts.  Who makes a fiber front site that is shorter then the one I have??
Is there a adjustable set of fiber sights that fit the PT 145,  or can fit it? Williams will be making a couple of different fiber sights next month  but they are not adjustable..
Any ideas  or just info on what gun sights are interchangeable??
Thanks
