We have a stock Gen4 G19 that my wife has claimed as her own. I take it out to the range a few times every year, and while I'm not a fan of it's trigger, I can shoot it as accurately as my Sigs. It takes a magazine to get used to the trigger. After that...no issues. I'm not spending money on after market parts for the G19, but I wouldn't hesitate to use it as a defensive weapon.
