The short answer is yes. I much prefer the Holosun w/Vulcan to any other RDS style sight I've used. I'm comfortable with the chevron although I will admit it will show hand shake much quicker than a 4-6MOA dot. I did get to test the pistol out earlier this month in a night shoot environment and the auto brightness worked flawlessly with a pistol mounted light and also a handheld light. Also, the Vulcan reticule works exactly as advertised from awkward shooting positions with your brain naturally correcting any sight misalignment based on the curvature of the outer circle you are seeing.
The longer answer: So I've been at the range quite a bit this week running drills. Specifically I was testing my draw & fire speed between my M&P Compact 2.0, one with RDS the other with Ameriglo Hackathorn sights (now the
Protector Series). Not surprising my draw & fire speed with the irons was ~0.15 sec faster on average. It started out a bit farther apart, but once I remembered to focus on the front sight with the RDS pistol instead of trying to find the dot alone the time gap narrowed. On a technical note the factory front sight is a mere .230in tall which in order to see it above the base of the RDS you need to tip the barrel up thus pushing the chevron up towards the very top of the RDS window. Although options are limited for the M&P (unlike Glock) I am strongly considering changing the front sight to a .420in tall version so the front sight post and chevron have more of a 1/3 lower co-witness vibe than just the chevron hanging out in empty space.
