kind of jumps the post but I disagree. Why do "mods" to the gun? To make it easier to shoot; hand fit, trigger pull, accuracy, assist in reloads, lights, lasers,...... "Mods" in a courtroom only come into play if the weapon had some mechanical malfunction and injured someone.
Regardless if you shoot someone with a STI/SVI that has been tricked out or a High Point; do the right thing and you are okay.
Compete with what you carry; it's great training that most CHL holders don't do.
