Wise A the problem is not the DA trigger stroke. The DA trigger stroke is short and smooth.
The problem is where it trips the sear and breaks the shot. On my duty guns........well.....on all my 3rd gen guns, the trigger trips the sear well before the trigger itself impacts the frame of the pistol.
On this one, it does not. And if I am not careful about my finger placement on the trigger, I can actually get it pinched between the trigger and the frame as the shot breaks. It is a trigger geometry problem, not a DA trigger stroke problem. Sorry I wasnt clear.
As to TDA triggers, I taught tiny housewives how to shoot DA/SA guns for 18 months after I retired. The much ballyhooed "Double action to single action transition" is only an "issue" on the internet gun boards. After watching little women who never shot a gun before, master it in less than 3 mags, I'm embarrased for those who claim it is a problem or disadvantage.
