I picked up a new G19/5 with FBI sights the first week out did not like the look of the FBI sights as much as the fact Glock ones they flow better with the slide I think . then the frame bevel . Well tonight I just traded it for a newer gen 19/5 with Glock night sights and the wonderful frame bevel . I just had to do it . but will keep my 17/5 the way it is . done deal
