I bought a used GSG 1911 and it came with a Fiber optic front sight and an adjustible Dlask rear sight. Even with the rear sight all the way down it shoots about 5.5" high at 20 yard. According to my calculations I would need a front sight of at least .250" to correct the differance. I really like the F/O front sight but I can't seem to find anything in Canada, or at Brownells, or anywhere that ships to Canada.
I was getting my calculations from here;
