Greetings: My brother is a LEO in Illinois. He's been using a Ruger P89 for 15 years but its ready to be retired. His bias again plastic guns has finally waned, and he asking his gun nut brother for advise. Department carry regs are wide open in regards to caliber and brand. Most LEO's I know carry the Glock 40, either a model 22 or 23. But my brother isn't a "gun" type guy, and only shoots to qualify as required. Would he be better served with the Glock 17/19? Thanks.
