I have been involved with the criminal justice system in Texas for years. I have never come across negative repercussions for gun modifications in all that time. The bottom line is use deadly force as a last resort and only if your life or someone else's is at risk, or if your home is being invaded. You are more likely to get a thank you from the local police as long as it's a justified shooting. I recall one case where a citizen was on his way to or from a range and came upon a police officer in a very bad situation, he used his handgun to save the officer. The local PD gave him a case of ammunition. This was in pre CPW License days in Texas.
