UMP Feeding Issue

Hello,

 

My first time posting here. I'm a manufacturer in Tempe, AZ and I recently took in 2 factory ump 45s. I don't have much experience with this platform and I'm getting consistent malfunctions in each gun. The round will feed and get stuck vertically and the bolt will close on it - see pictures. Sometimes, this will happen every three rounds, other times, I can make it through an entire magazine with no issues. At first, I thought this might have been a magazine issue with a particular magazine, but it happens on all eight factory magazines I have. Using Magtech Sport 45 ACP AUTO Ammo 230 Grain FMJ and would like to stay with that if possible. Any advice would be appreciated.
