looking to impulse buy an optic for my OR P-10S today and have it narrowed down to a holosun 508Tv2 or an RMR. The holosun looks much larger / bulkier, anyone happen to have a pic of a p-10S with a 508Tv2? If i go RMR, whats the latest 2-3moa version?  Ideally would love an SRO but out of my budget

My P-01 should be done getting milled in the next few days. I have a 508T going on it. I have had RMRs mounted before, but cannot see how it is the better option vs the Holosun. I'll update with pics and opinions when I can.

In terms of size, they're basically the same.  The Holosun is marginally larger, but still nowhere near as big as the SRO or DPP.  This is good for me - still concealable, less blue tint, the larger window makes it that much easier to track to the dot in recoil.  I have 3 RMR's and once my annual battery changing session came around, the holosun stayed on my carry gun (P10c)

Different pistol and sight but I have a G19 and 17 with a 507c and 507cv2 on my pistols.  I originally had RMR type 2 but I had a run of bad luck and got some bad sights.  I like the RMR a lot but I kind of got burned so I tried the Holosun since it used the RMR footprint and turned out to really like them.  The window is slightly bigger which I like more than the RMR and the shake awake/solar panel/multi-reticle(I use just a dot) couple with the price sold me on the Holosun.  I have close to 4K on my first 507c and still using the first battery with it being over a year old now.  Eventually I might try the RMR again but currently I am just to happy with the Holosun line up.

Disclaimer I did get a 407cv2 first but when I received it from the moment I opened it up I was suspicious I had got someone's return.  The windage adjustment was seized and appeared like someone had got red loctite in or on the adjustment as I scraped out of the screw head slot what appeared red loctite coupled with a fingerprint right in the middle of the front glass.  I did return it and got a 507cv2 because the place I ordered it from was out of the 407cv2.
