Shooting a gun with an easy trigger and clear sights is good practice. Shooting a gun with a difficult trigger, especially depending on the size of it, is even better practice. I got spoiled by H&K's and other expensive SA/DA stuff when I was learning. I've now entered into DAO territory for the...third time. Not counting revolvers that, if manually cocked, had some of the lightest, smoothest triggers out there...a good old Colt .38 (varous police models are very affordable) will teach you how well you can shoot with an odd grip and bad sights. Answer: surprisingly well.
But I had a P250 sub (gone now) and now this P239, and two Kahrs, which kinda count. They are decidedly not real DAO...their function is much the same as a Glock, but they purposefully have an extra-long 'DA-style' trigger stroke. It's hard to complain about the Glock trigger, because they're light, short, and cushion your finger just enough to avoid jerking the gun upon firing. Any mushiness or graininess is a moot point and doesn't really affect how well they can be fired. But this short snappy trigger is why I would never carry one. Or similar pistols.
Focusing while the hammer is rising and knowing when the drop is coming is what has to be done to master this gun. And consistently finding the short reset without even thinking or slowing down.
Rude, since, unfortunately, you cannot use my 'hey, it's DAK' excuse :awe: ...I think you just need to focus on your grip, aiming, breathing...make sure you're doing all the simple stuff right...and in SA on that gun, shots will just start falling into place.
