If it were up to some people, all that would exist and be an option would be striker fired micro 9mm and double stacks. They bash everything else from 1911s, revolvers, and DAO, and even DA/SA guns using the excuse that companies should make more striker fired pistols because they sell more.
Kahr double stacks aren't going to sell well. That market is already saturated. Changing the Kahr trigger to be yet another striker fired trigger with a dingous just like all the millions of others isn't going to increase Kahr's sales either. It would just be more of the same, and I doubt all the people who bash Kahr because they don't have the know how to shoot even a great DAO trigger well, because they do not have the wherewithal or skill, STILL wouldn't choose Kahr over the other alternatives. The only people who would be interested are the same people who are currently interested in Kahr DAO single stacks.
Kahr doesn't need to change the DAO trigger. The trigger is already phenomenal. If someone can not do well with it, it's a training and skill issue on their part that they're trying to blame the "long" trigger for. I own all type of triggers, nearly 100 firearms, and I've yet to come across a modern stock trigger that I couldn't shoot well. Different or non competition/target like aka short and light doesn't equate to being a bad trigger. SAO, DA/SA, and striker-fired trigger stock and aftermarket are all their place, pros and cons. One isn't necessarily better than the other. Anyone who is use to shooting revolvers and DA/SA handguns love and know how great the Kahr trigger is, and they generally can shoot and appreciate any type of trigger. Those who are primarily familiar with polymer Glock like handguns are the ones who take issue.
What Kahr needs to do is to refine and update what they already have with new designs and a new look. They need to update the look of their steel framed guns, add more calibers like 45acp and 10mm. They also need to adjust their price point to be more competitive. They should also add double stacks and even aluminum frame options to their metal frame guns. Their single stacks should become staggered stacks at the grip while keeping the same slide dimensions for backwards compatibility in the aftermarket. They should stick to filling the nitch that they're known for, but add more modern features. Basically what Glock, CZ with their 75 line, and Beretta with their 92 line have done for decades.
