Shooting with a rmr without backup sights.

Plan on getting a custom slide with rmr for the Glock and not using the rear backup sights as I’ll be putting a slide racker on it.

Every picture I see online of a Glock with a rmr has iron sights for co witnessing. Almost think it defeats the purpose of getting a rmr or is it a must with this gun?

What are you thoughts about this?
 
Backup sights are exactly that. It’s not a Glock specific thing.

If you totally trust your RMR then don’t worry about BUISs. But that Murphy guy....I tell ya!

If you’re going with the BUIS, you need the tall suppressor height ones for a true co-witness.
 
The tall sights are also frequently used to help you pick up the dot easier when you bring the gun up.

Most pistol shooters index the irons in line with their eye naturally but struggle to find a dot in the same way.

So the irons help to index the dot into alignment with your dominant eye. The other way to do this is to stand in your house and practice presenting your rds equipped pistol thousands of times so that it becomes natural.
 
How does the slide racker attach? Is there one that fits a sight dovetail?
I insisted on a rear sight when I got my slide milled, thinking the training wheels would help find the dot, which they did...for the first bit. As above, if you practice your presentation at home, you will find the dot (ingrain a respectable draw into your muscle memory), and the sights quickly become superfluous, IMO. If I get another RMR equipped pistol (Trijicon for the win), I'll just keep the front sight.
Dryfiring with a dot is excellent, I find it really fine tunes your grip/draw. I drew consistantly high, to start.

Oh, and the RMR makes a dandy slide racker, I Aaron Cowen'd the crap out of mine against posts at the range, no problems.

Edit:....so after having a supressor height rear take up a third of my dot window, I put in a normal height rear sight. It's barely visible over the optic base, and the front sits way high for a centered shot, but meh. They're back up sights. If I could find a set of...low supressor/tall regular sights with a tritium front, I might try that next. While happily making easy hits at 25 with my dot:).

Yes. The slide racker fits in the dovetail. I wonder if it’s a lot harder to track the dot because it’s on a moving slide oppose to open guns where the dot doesn’t move
 
if it's for sport back up sights are a waste of time, if it was for daily carry that's different.
 
^ What Slavex said. Unless this is for defending your life (which it's not in Canada) go with the optic only. Plenty of USPSA/IPSC guys only have a red dot and they trust that to win World series. As for not finding your dot when you draw the gun or transition, that is called poor training schedule. It is something you need to practice, just like finding your irons and being lined up.
 
No co-witness sights on my Open gun and haven't had any issues...I have factory co-witness sights on my Production Optics gun and I can't say I even notice them...So, if the gun comes with them fine, but if you have to add them, I wouldn't bother.
