It is true hammer fired guns, at their best have better triggers. The gap had narrowed though.
The current generation of striker guns have pretty darn good triggers. Walther deserves a lot of credit for setting the pace with that.
Walther is again pushing the envelope with their Expert comp trigger. They are not the only ones.
It's also not a given that hammered fired guns have better trigger pulls. I have an HK45 and an HK P30sk. I have absolute faith they will go "boom" when asked. Build quality and accuracy are top notch. But the triggers??? Meh...not very good to be honest.
At the end of the day, the simplicity and cost effectivenes of striker fired guns will rule the day. They are easy to build, operate and maintain.
It's easy to predict striker triggers will continue to improve. Perhaps soon, the norm will be a pistol with a clean, 3lb striker trigger and a manual safety of some sort. Homage to the 1911.
