I've shot some pistols with small red dots on them and I didn't like it. The bigger dot works better, at least for me.I also think that's a little bit big. An 8 m.o.a. dot at 100 yds. has a diameter of 8.3775968 inches. A 4 m.o.a. dot is easily picked up and seen at 100 yds. Just my two bits.
Here's one place that does it. http://www.bowietacticalconcepts.com/pictures.htmlI really want to put an RMR on my M&P 9mm or even my Steyr if possible.
I thought I had a couple other places bookmarked, but can't seem to find them now. I'm tempted to throw mine on the mini mill and try to do it myself. Maybe I should practice on a Taurus first
Red dots on pistols have been around for quite awhile, but most folks poo-poo them. I never really could figure out why because if you like a red dot on your carbine, then you'll like it on your pistol, too. I think it took a major manufacturer (FNP-45 tactical) to start making them for it to become mainstream.Every advantage the RDS gives a carbine is also applicable to the pistol, which is why our students train with their RDS equipped pistols out to 200 yards.
