Think it had to do with how deep it had to be milled
Not really. The two people I know who have used them ended up turning the circle off after a little while. In the very minimal amount of shooting I did with one both the circle and the chevron reticle seemed distracting. Most people I know who go with the standard Holosun circle-dot (32MOA circle/2MOA dot) end up turning the circle off as well.
I like dots and I like the 8MOA 407CO ring (with corrected vision). I've also had good results with the Holosun circle-only reticle, especially to mitigate glare, but shooting one-handed it was way to busy in movement.
As to directly answering what you asked regarding novices, I think reticle training wheels may help in the beginning, but encourage a "visual" presentation rather than a kinesthetic presentation. I want my vision on the target/threat - not trying to find a reticle or a map to where the reticle is (the ACSS).
Thank you sir.
I am breaking into this genre of optics as a septuagenarian former military (RVN) and (long retired) 32 year LEO. I am familiar with rifle/carbine mounted RDO's, starting with the Armson OEG all the way to current products.
I recently acquired the S&W M&P 9 M2.0 Compact 13568 after using Glocks since about 1984-85. (1st Gen Austrians). I will probably go to a Holosun 507 variant, and the 99.9% use will be CCW.
I am thankful for the erudition and body of knowledge that you and others provide on this forum.
This is 180 degrees from a press out, where you try to get the sights/dot into your vision as early as possible, and drive the dot to the target. You are advocating looking at a spot on the target, and using your index to present the pistol, at which point the dot appears on the spot on the target.
Likes pretty much everything in every caliber.
It is readily apparent that both of you are emblematic of the development of this system that has gone from a potential to ubiquity in a about a 5 year time frame.
Thanks again for the subject matter expertise.
