The PX4 does not have an extremely long DA trigger pull, as a matter of fact it is quite short and crisp for a DA. SA a little sloppy? I don't know what you are referring to there. Shoot a Sig P226, CZ75, Beretta 92FS or H&K USP with a stock trigger and then tell me how extremely long the PX4's DA trigger pull is? It takes much more to master a DA/SA over the consistent trigger pull of a striker fired pistol generally. Stick with one or the other would be my suggestion. The more you practice the better you get.
