I need help with picking a red dot. I know I want to try a red dot on my P365 and possibly on my Springfield XDm .40 down the road. Both pistols would need to have the slide cut for the optic. So, while it will be expensive, at least I’m free to pick whatever I want. I will not say ‘money is no object’ when picking a sight, but I’m not entirely sure I want to jump into the most expensive RDS out there, right off the bat. My thought is to try a dot on the P365 and then, later, possibly try it on the XDm. All the options combined with the multiple footprint types has my head spinning. I like having options and the fact that each footprint is only compatible with a couple of types of sights is really frustrating me and making it nearly impossible to make a decision. I keep talking myself out of each one I think I want. Lol! So, I’m hoping y’all can help me decide. Why these manufacturers don't get together and settle on a STANDARD mounting footprint is mind-blowing. It sure seems like it'd make life easier for everyone.
Does anyone know whether the new Holosun 507K uses the same footprint as the RMR? I believe the 507c does (hope I have that right?) so I’m hoping the K model does as well. That would let me start with an inexpensive sight and, if I ever wanted to, upgrade to the RMR (which seems to be a Tier 1 option) later. <—-Sort of a win-win option in my book.
Here’s a list of the brands I’m considering
Holosun 507K (3.25moa). RMR Footprint
Holosun 507c (3.25moa). RMR Footprint
Trijicon RMR. (1moa or 3.25moa). RMR Footprint
Leupold Delta Pro (2.5moa). Shield Footprint
Vortex Venom (3moa). Doctor Footprint
Vortex Razor (3moa). C-More Footprint
Am I missing a brand/model that I should consider?
I’m really leaning towards starting with a Holosun because I could always switch to the RMR and that footprint offers me 3 sight options. The other footprints only allow me to mount ONE sight each. Question: Are there adapter plates and, if so, what are the negatives of using an adapter plate? Say I started with thew RMR cut but, later, wanted to put a Vortex Venom on there?
Last questions… What about co-witnessing in case of sight failure? Should I have the slide cut placed in front of the rear irons and switch over to suppressor sights, just in case? The Holosun 507K looked (see video linked below) like it may have a rear iron sight built into it - is this the case?
Sorry for so many questions in one post but I’m hoping that, by throwing all of it together, it’ll make it easier to get useful suggestions. Thanks in advance to those who reply!
Even though this still image doesn't look like it, this video (first few seconds 0:13 - 0:16) makes the Holosun 507K look like it incorporates a rear iron sight; but it was a prototype, so maybe its not in the production model?
