Alright, 22 yrs old just graduated from the police academy and finally have the money to invest in my first piece. Im stuck between the glock 19 and glock 23 both gen 4's. Ive shot both of them and really like both and more importantly shoot them each pretty well. Only question if i decide on the 19 gen 4 should i get the newer 0-4 spring? Ive been going back and forth between the two for months and now its time to make a purchase, just looking for some advice...
