Sig Romeo X Pro Enclosed.
Had to grind the locator pins to reduce the head height, but I like the way it sits so low on the slide.

I'm in the same boat. I'm new to pistol optics and the RXM. I'm running a Vortex Defender CCW, no modifications needed. I think it's the perfect size for a Glock19 sized pistol.

I'm running an EPS Carry, It direct mount's using Tacrig pin's.
I'd also consider a full size EPS in the future.

To clarify the Holosun SDS for the Sig P320?  Could you post a pic of that?

I installed a Vortex Comp Dot.  Big optic but I am anticipating the full size frame.

I'm not him, but SCS 320 is the SIG version which is the DPP (Delta Point Pro) footprint.  It's been pretty popular on the RXM and Echelon.

I just have not seen it yet.  I don’t have OCD so the mismatch would not bother me.  (If there is one)

Holosun 407 C.  It’s what I had on hand when I bought the RXM.  

Swapped grip modules for a black one.  Super easy.

Is the RXM supposed to come with the different posts to accommodate optic types?

I just realized mine did not. disregard, it actually did.

Not sure I'll ever add an optic but, curious nonetheless.

Ruger sells replacement pins if needed for the RMR, DPP and RMSc footprint optics.

https://shopruger.com/Pin-Trigger-RXM-Pistol-Set-of-2/productinfo/68131/



If you're wanting to use a Holosun K-Cut optics, you can order a plate or aftermarket locator pins for the Holosun K-Cut optics.  

Tacrig link

DPP makes a plate for the K-Cut. (Full disclosure, I just got one of these for free through the Amazon Vine program, but haven't used it yet).

Mine is currently wearing a Holosun 507c.  Good fit and co-witness with the original sights.

I'm thinking of replacing it with an Osight S or SE.
Nobody is coming. It's up to you.

I’m trying out the OSIGHT SE. I have a few other handguns with the Holosun EPS. Just be aware of the locator pin height.  I filed mine down before I became aware of the Tacrig pins.

Vedder Light Tuck. G19/TLR-7. I have a SideTuck on the way but this one seems to be working fine. I have about 100 rounds so far without a hitch. Which isn’t a whole lot, but I did deliberately use both the OEM Magpul mags and Gen 3 Glock mags. I made no adjustments to the sight itself once I had it mounted right. It was dead on at 15 yards with 124 grn AAC.

Good to hear, I've yet to get mine to the range and intend to use both gen4 glock and magpul mags.

I am also using the Osight SE like the poster above. My only issue with the optic is the fact the circle is a bit more like an oval rather than a circle top to bottom.

I’d want the SCS320.

Had a cheap holosun I had on hand, just got a good deal on an RCR, so I’m going to try that out, see how it works.

Anyone else tried that?

I went with the Primary Arms SLx RS-10R.  Improved over the previous version and now in RMR footprint.

Mentioned in the RXM thread, RCR doesn’t cowitness with the stock irons, unfortunately. Was also strangely loose-fitting on the mounting bosses/pins.

The capstan screws were oddly tight, thought they were the wrong thread pitch for a moment, or cross threading. Nope, just really tight for some reason.

But it works, no issues after a few hundred rounds, zero held, nothing loose.

Little interested if anyone has mounted up an RMR-HD, per the math, it overhangs the ejection port a bit more than I’m comfortable with.

Osight SE Green 6 MOA dot.

I added a fullsize frame to my above pictured RXM with the Vortex Comp Dot.  My only critique is the deck height which obscures a co-witness.

I found a second RXM for a good price and added an enclosed Vortex Venom red dot for further eval.  I like this platform for the $.  The Venom enclosed has a tall deck also.  I have a full sized frame for this one too.
