People ask me all the time: “Irons in front or behind the optic?” In my opinion… it doesn’t matter. I believe both have enough pros and cons that neither is majorly superior over the other. When I shoot either of these pistols I have never once thought “wow, something is off… I can’t shoot this as well as the other because of the rear sight placement.”
Concern yourself with developing actual skill. Because THAT is what matters.
