Of course there are advantages to different platforms and I am not saying that all other styles will completely go the way of the dodo but they will move to a niche market. They are pretty much there already. Look at your list compared to the gun market. It is the minority not the majority. There are real reasons for that. Shooters skill is only of the the factors pushing strikers forward. Pretty much every old school traditional DA/SA is trying to grow their striker fired line up because their DA/SA sales are lagging behind. You are completely overestimating the avg gun owner in this country. They don't shoot tiny groups with any guns. They don't put in any time. I see it everytime I go to a public range. The avg person not only does not "train" they do not shoot very often. I know people who carry but only discharge a firearm about once every 6 months and even then only a 100 round or so. The platform does not change that fact. Go to any gun games style competition you will see striker fire and SAO dominating the landscape. This is not sterile shooting on a square range. Even if you remove that from the equation the learning curve is shorter on striker guns than it is on DA/SA. Ask Langdon, Vickers, Bruce Grey, Pincus, Leathum etc... They will all tell you that learning to shoot a DA/SA gun well takes time. It is not that you cannot learn to shoot them well. People do it all the time but it takes more time and the vast majority of the shooters do not have the time, resources or desire to put the time in. The honest truth is that most gun owners won't ever "master" any platform. This does not mean people should own one but IMHO its just the reality. The rest is completely conjecture. Are you trying to make the argument that before striker fired guns there were no NDs? it seem like it. The platform is no substitute for the safety between your ears. If a person is negligent enough discharge a striker fired gun they are negligent enough to ND any platform IMHO. A long DA trigger pull is not a substitute for practicing safe gun handling skills. Time will tell if I am wrong. In the end it will not effect me much. I have more DA/SA guns in the safe than I will ever be able to shoot to failure in my lifetime. I will be worm food long before my DA/SA guns fall apart and if I get the bug to get another one even if everyone on the list stopped making them today there are millions in the marketplace to satisfy my needs at any and all price points.
