i love the pistol and it eats ammo like a junk yard dog! not one jamb in 1000 rounds. only problems so far are:the plunger tube(for the thumb safety) became wiggly/loose ( My segeants operator also did). the rear sight had no adjustment bolt in it when i purchased the pistol. how-ever the customer service is glorious! fantastic service and nice people. i use the operator every day-on and of duty. very happy over all. great pistol!
