if you want the gold standard then the trijicon RMR. All depends what your use is for it
Yep. All depends. The SRO won't hold up to duty use. But is excellent for all other applicationsThe Trijicon SRO will give you a better and bigger sight for acquisition of target. It all depends on what you you plan on doing... and it was designed for pistols but according to Trijicon it will handle the kick of my 12 gauge also.. easy to swap around too!!
If the slide is cut for a RMR then only sights that use the RMR footprint will fit (unless you want to use an adaptor plate).How ya figure that?
