I'd have to say if I prefer straight double action, if there is to be any double action at all. I don't like going from double to single after the first round. I'm sure it doesn't matter a bunch in the heat of the moment, but since I don't draw to defend myself (and hope to never have to,) and am not in a combat situation, I find I prefer not having to make the adjustment at the range. That being said, I like my single action only P320 for both the range and carry the best.
If I could get a mix of the HK LEM trigger with SIGs SRT id be a happy camper. I tend to shoot DA and SA better than Strikers. I also like the safety barrier since I wind up apex carrying often. If you are in a hurry anyone including well trained people can have an accident. Im not well trained and any extra safety I can get while not using a safety is nice.
