New Guy Here w CORE Optics & Co-Witness Question
I have read a whole lot of stuff on the web in the last two days and am confused. While I see some people say some models Co-Witness and others say that same model does not. I want to get to the bottom of this. I would think S&W would help out! Can this forum?
The question is, Which red dot sights not only work, but provide totally unobstructed co-witnessing?
[/U][/B]For example, the gun I bought used, CORE 9mm 4.25" came w a light and a Burris Fastfire II. The sights are barely useable to co-witness due to part of the front sight being obstructed. One would have a tendency to shoot high with the iron sights as a result. I could use this site on an AR, but am not happy with it on the S&W CORE.

Welcome to our little corner of the web.
I have a 5" CORE with a FastFire 3, co witness is marginal, I also have a Vortex Venom and the co witness is marginal on it also. The manual that came with my CORE listed 3 or 4 that would co witness, but several of those models are not available anymore, they have been replaced by new models, several of which won't co witness at all. Some of the models listed that will co witness are exorbitantly expensive, 2 or 3 times the price of a Vortex Venom.
IMHO when you mount a red dot on a CORE, in most cases the only way to use the iron sights is to remove the red dot.

Co-witness is great with a Trij' RM06. It's all about height, red dot base height. I have no experience with other micro red dot sights.

Nice to meet you all too. Thanks for the info.
I am going ahead and ordering the Trijicon RMR Dual Illuminated w a 9 MOA green dot. If I want to do precision work I'll switch back to the Burris Fastfire w 4 MOA. I cant believe the RMRs are the only ones w true Co-Witness. Seems to me S&W would work more w these companies to make that happen. Otherwise I would just as soon have standard low mount Novaks on a milled slide. That Jpoint looks like it might have a better Co-witness than the Burris, but I cant tell for sure.

I have tried the big triangle and it covers to much of the target for any kind of longer range work though you can use the tip of the triangle, why make it harder than it has to be. The dual illuminated models can have the dot wash out if you are in a shady or darker spot and shooting out into a more brightly lite area. Choose what you want but this is all knowledge gained from actually daily carrying and shooting RMR equipped guns for 4+ years. Hope this info helps a little.

Check out the VORTEX red dots too, they have a couple nice ones, and a LIFETIME warranty, but you probably wont ever have to use it.
Watch out for the chinese RMR knock-off`s, they are junk. They look almost identical to the real RMR`s, so be careful before you purchase.
I added a video in here so you can see the differences (this is not my video, it belongs to someone else)
Trijicon RMR vs knock off RMR
