Ultimately, it's your gun. Do whatever you want with it.
The reality is that practice makes perfect.
If you can't make a basket, practice, don't lower the basket.
If you can't pass a test, study, don't lower the standard.
If you don't shoot a Glock well. Practice, don't lower the trigger weight.
For me, when it comes to guns, I refuse to do anything that compromises safety.
If your gun has a 4.5lb trigger pull, that's actually not bad. If you, like a lot of people, have a sub 3lb trigger pull, you're (in my opinion) compromising safety.
As far as nitpicking the random article I posted, I could easily post 100 articles about how extremely light triggers contribute to ND's but I don't have the desire to waste my time researching something I already know.
