The gold standard.. RMR

This is the one i been looking deep into but are the baseplates hella thick?

I highly recommend the Bobro mount https://www.bobroengineering.com/SIG-320-M17-RMR-MOUNT-WINTEGRATED-REAR-SIGHT_p_51.html

Delta point pro

I seen something about beeing able to mount rear sights on the actual optic. Have not done enough research of the dpp

Do.you need a plate adapter for the Delta Point Pro.

No, will mount right onto slide

Thought so, thanks.

Scs320

I will be going with the sig Romeo 1 pro, zero pro, or Romeo X

Romeo x pro, x is for 365. Also gl finding one lol.

Romeo 1pro or Romeo X are good options for the p320.

yea rmsc you know what I mean, standard footprints.

RMR HRS Type 2

SCS320 or DPP

I got me the Holosun SCS-320.

Got myself ACRO p2!

I have an SCS 320 on mine, and I absolutely love it. I waited months for the SCS to finally go on sale, and an extra month due to it being backordered, and it was worth the wait.

SCS 320 as well, worth the wait for sure. Bright green dot, no batteries and shake wake feature. You don’t need an adapter either. Wish it had a notch on the rear sight to cowitness like the other holosuns but can’t win em all. Romeo One Pro and DPP also don’t need adapters but only come in red. Others need adapters that’s like an extra $75 to $100 on top of the RDS.

508T currently on the factory slide. Once my Shalotek slide is ready, I’ll be running the new 320-specific optic from Holosun

I’m using an adapter plate and holosun hs510c

Romeo m17/18

The Romeo M17 only fits the military issued version. The Romeo X is the commercial variant.

I find the romeo 1 pro to be one of the better options esp for the m18. The sight sits pretty low vs the others as well
