glocks wont go bang unless the trigger is pulled. get your self a good holster that covers the trigger and youll be fine
. ive been carrying my g23 IWB for a few years now....that being said carry what your comfortable with. if a glock is gonna make you so nervous that you wont carry all the time then dont get one. but seriously theres nothin to stress about. just dont pull the trigger while its in your pants
