Why didn't the paddle mag release ever catch on? It is physically impossible to accidentally drop the magazine while holding the gun normally, and it's still quick to reload unlike the heel mag release. It is objectively the best type of mag catch/release system for a handgun, and it has fizzled out. Why? It took only ten years for the entire handgun industry to offer optics-ready slides, but in 40 years or so, the paddle could never gain any widespread appeal even though it costs nothing more than a button release. Why must it be this way?
