I don’t see anything wrong with double/single action pistols.
When I had a P-226, the Decoker was the safest way to put one in a safe condition. If I knew I was likely to need it instantly, it would be cocked and ready.
If I was just walking along and might need it by some chance I would carry it hammer down on a live round. The DA trigger was pretty good and I could cock it faster by just pulling the trigger than by pulling back the hammer, and I would have a fair chance of hitting my target too.
Yep, there’s a proud believer in “the cocking shot.” More power to you, whatever works for you is best. I just believe in one trigger pull first to last, in any pistol. Different strokes.
