I've seen this question posted before with no answer. I do not want to replace the FNX 45 sights with a sight that will duplicate the factory sight point of impact. I use Hienie slant pros. So all I am looking for is the dove tail specification. I don't need a link to MGW and the trijicons. What I'm looking for is to find out if the cut mimics glock, HK, Springfield etc. I expect it is going to be a mix and match and a good bit of fitting but with the dovetail dimensions I have somewhere to start from. Any help to these ends is greatly appreciated. Thanks!
