Best replacement sight options for CM9?

[gb6491]

I want to replace the front sight, and I think the Dawson Precision ones are probably as good as any... but I am confused as to which one to get: https://www.dawsonprecision.com/Prod...7B7-1388518379

Why are there different heights? I just want something that is the same as the existing front sight, but not invisible in low light. Which one should I choose for that?

The different heights allow for elevation correction. You can measure your existing front sight to verify, but I believe you'll find it's around .175
Dawson's .180 is close to that, but it could move the point of impact down a little from where it is with the stock sights.
Regards,
Greg


Edit: I was able to find a taken off CW front sight and, after cleaning up the remains of the two posts, found it measured .180" tall and .140" wide
