it would be interesting to see an actual case in which evidence of a modified trigger was used to convict someone of homicide. That would really answer the question.
You're asking the wrong questions. The question is not "can a modified trigger get me convicted of homicide?" The question you should be asking is "how much can a modified trigger complicate my defense?"
There are a handful of cases out there where a trigger comes into play. For example, in the case of
People v. Magliato, there was evidence of about the weight of the trigger (DA vs SA, not necessarily modified), and that evidence was part of the body of evidence used initially to convict the defendant of some degree of murder. The appellate court eventually reduced the conviction to manslaughter, but that doesn't mean that the modified trigger didn't complicate matters. Appeals aren't free.
In
State Farm Mutual Insurance v. Partridge, Partridge had lightened the trigger on his .357 Magnum revolver to a "hair trigger." While out hunting jackrabbits, he had an ND, striking the passenger in his car, & was sued for personal injuries. From the decision: "Prior to the date of the accident, Partridge filed the trigger mechanism of his pistol to lighten the trigger pull so that the gun would have ‘hair trigger action’; the trial court specifically found this modification of the gun to be a negligent act, creating an exceptionally dangerous weapon."
State Farm Mut. Auto. Ins. Co. v. Partridge, 10 Cal. 3d 94, 97 (1973). This isn't a SD shooting, but is an example of another way in which a modified trigger can be a problem.

WATCH LINK I POSTED. The link I will provide is a pretty good look into the legalities of modified firearms if you had to use one to defend your life. Basically, the gun shop worker who told you that has fallen to the brainless thousands who regurgitate what they here from other people or on the internet. Watch this video, very good information.
I don't have any speakers on my home computer, but I'll watch it later. That said, I'm not confident that YouTube is a good place to get your legal information.

There is no reason to fret about modifying your gun. the biggest argument is that "the defendant modified his gun to more easily shoot people" which is complete BS and can easily be fought in court, in the RARE case they did use a line like that.
How easily? What would it take to "easily" fight this in court?
The reality is that, by the time you figure out if your gun mods will be an issue, it's already too late to change course. That ship will have sailed. If you have to fight a courtroom battle over your gun modifications, you'll likely need experts. Depending on the modification, your expert may have to test the modification and write a report. If the 1st expert doesn't say anything beneficial to the defense, you won't want to use that expert, and may need to go looking for a 2nd one, and so on, until you either find the right expert or run out of money. Don't expect experts (or the legal fees to find them or review reports) to come cheap, either.
