A few months ago I was passing around that crap as well. I bought into the idea that gun modifications could increase your chances of going to jail. Then I was challenged with a post like this on a Facebook page. I went to find evidence where that was the case. After two days of searching I couldn't find anything.
I agree with the above completely. As long as your modifications are safe then this won't be an issue as long as it was a good shoot. If you get sent to jail, then it was because there were other questions. Not because you changed you grips, had a trigger job, changed your sights, etc.
