You're making a mistake by passing on this gun.
First, of course GGI will tell you that their comp trigger job is for competition only. It is called liability. They market it as a competition, they don't know who you are, they don't want a headache if you shot somebody accidentally and said they had told it was OK. They may have their own philosophic position on this and other issues that others may or may not share. As an example, Bruce Gray has spoken publicly against appendix carry as an unsafe method many times and there are a lot no less switched-on people who have an opposite opinion.
The linked article is a good example of unsupported noise on this subject. That any aspect, including gun modifications, can and will be explored in civil tort should be presumed apriori. In that sense, the article is a statement of obvious. What's missing is an evidence where any aftermarket modifications were a cardinal reason or even supporting evidence for an unfavorable verdict. More so, the discussion below showed a legal example where aftermarket trigger was attempted to be exploited and failed.
Your primary responsibility is to assure that the shooting is legal. Your second responsibility is to assure that you hit what was intended to be hit and good trigger helps. You third responsibility is to hire a competent attorney regardless how you well the fist two things worked out.
There is no industry standard on how light the defensive trigger should be. Head out to a Wilson Combat website and look at their line-up of 1911s designed for carry and duty. CQB, Tactical, what have you. They come with trigger weights starting at 3.5 lbs and effectively no takeup, especially comparing to LEM. Including models endorsed by and named after Ken Hackathorn and Larry Vickers, two of the most recognizable defensive pistols instructors.
Besides, who says you can't use a competition gun for home defense? I have a purpose built competition-only Tanfoglio with 2.5 lbs trigger but if this is the gun that's closest to me when bad guys are breaking in, rest assured I am not going to go digging into my safe for a street-legal gun. Go shoot a couple of matches for a supporting evidence of being a competitive shooter and don't lose sleep. Don't buy into bullshit.
