I have the Springfield loaded model in 9mm and have had a long series of problems with it feeding. I have tried all different kinds of ammo and both of Springfields two different style 9mm magazines. It seems that Springfield makes this gun sometimes with a ramped barrel and sometimes with a non-ramped barrel. Mine is the non-ramped. Many shooters I know say getting the ramped barrel installed will solve my problems. I do know of one individual that had this done and swears it did solve his feeding problems. Just want to know what others think about this?
