When you reference Law Dog job I read law enforcement officer, if so I can understand department restrictions on customization. Do you think the attorney was implying that civilians or off duty police carrying personal firearms should likewise not customize?I personally would not modify what I carry for CCW, it rests legal problems.
This was told me by Defense Attorney in AZ, who specializes in defence.
Know when I carry sidearm in Law Dog job, we had strict guide line on Trigger Pull for both Duty & Off Duty Firearms.
Rangemasters did random checks to keep everything in spec.
It was all about prevent or being able to defend litigation.
