My husband owns an S&W Performance Center M&P 9mm M2.0 Shield and I own a S&W Performance Center M&P 380 EZ Shield. Both say they come with HI VIZ fiber optic front and rear sights. The front litepipe fell out of the 9mm and is lost. I am trying to find out the correct litepipe size, model #, etc. each gun uses, in order to purchase replacement litepipes. I think the EZ uses "replacement litepipe handgun #5". Can anyone confirm that and also tell me what size the 9mm uses? Thanks.
