I tried the Trijicon RMR "red dot" sight the other day at the range on a G19 and now I get it. It's the future of pistol sights. It's miles better than iron sights. I would think Glock would have recognized this and would have offered an MOS version of every handgun. It's surprising that that they only offer a few models in MOS. Just curious how many of you have tried red dots and what you think of them. I'm really disappointed the G23 and G32 are not available in MOS.
