I don't like Glocks. They feel like a brick in my hand and I hate DA only systems. I tolerate DA/SA simply for the safety aspect of not having to carry with the hammer cocked. Just never could get that squirrelly feeling out of myself when holstering a chambered and cocked firearm. Got pretty good at cocking on the draw but the DA feature does allow for that instance of goofup. No shooter on this planet can be as accurate with a DA as they can be with an SA. That long and heavy trigger pull can and will effect barrel movement left or right. That little 1/8-1/16 inch movement of the barrel could very well mean a hit or a miss at 20 feet. I like to do my very best at eliminating as many possibilities of a miss out of the equation.
