No, the DA/SA trigger is the same every time out.
First shot is a long DA pull between 8-10 pound usually.
Then there is a transition which is the same every time.
Second shot is a shorter travel SA pull between 4-5.5 pounds usually.
These things always happen in this sequence, so it is consistent and can be trained for that way if one is not lazy.
Complaining about the DA/SA trigger is a lot like complaining about the possibility of "forgetting" the 1911's thumb safety.
Both are mere training issues.
Leave the gun, take the cannoli.
