I'm seeing this long after the OP first posted (sorry about that) and don't know that HNI would necessarily create that sub-forum although it's doable. Currently, the Guns sub-forum within the Firearms section is a catch-all forum for these types of questions and has some really good discussions on CCW issues, etc. Posting a topic about night sights in that forum is totally appropriate and would likely get the most responses out of all the forums (IMHO).
