Thanks guys! With all the information from this thread and all the other threads I have read on the subject. I decided the quinn II is the mount for me. I have shot both types of mounts, the upright on my open glock 34 and cheely on a para 9mm I built for a coworker at the indoor range/ retail store we work for.
The things that I like the most about quinn is the smaller variance in zero impact distances. With my upright mount on my glock zeroed @ 15 yards I was way off at varying distances. I think it will be an easier transition moving from my limited apeiro iron sights to the quinn dot.Most of all!!!! a higher degree of reliability. I will ALWAYS take function over bling ANY day.
