Nice sight-dovetail wide - Lyman Series 17A Target Front Sights

Bought this to replace the factory sight on a Marlin 39A 22. Got model AHB due to the feeling that the 0.404 height would work best in my application. The issue I have is cosmetic. The dovetail base is about 9/16" wide. The front sight ramp is 3/8" wide. So if centered on ramp, there is 3/32" sticking over the ramp on each side. I wish it was narrower, or at least it was easier to cut down. If trying to cut it down, it would require blending the curves near bottom. And I assume some re-blueing
