Hi, I have a bit of a problem, I have a Winchester M94 circa 1950 (32 spl) and the bead has been broken off the front sight. Now all the sights I can find at Brownells, are too wide (all marbles are .340 wide), or too narrow or too wide. (williams are .250 or .340), the width of the broken sight is .290. what do i do, just buy the .340 wide site and take .025 off each side?
