...they have same plane apperatures...so you don't have a change in you point of impact in elevation when you flip from one to another...
...if you are going with the Samson rail...i would personally use the Samson Sig specific folding front sight that mounts directly on the gas block...giving you a slightly longer sight radious...although the Troy front sight will work just fine mounted on the Samson rail...
