This happens too many times... Far too many times
In the second timeline, the machine pistol jams constantly. It's not accurate to start with and every trigger pull fires 3 rounds so with a mag of 21 you essentially have to reload after 6 trigger pulls. Reloads are slow and in the 2nd timeline things happen faster with the result that you constantly pull the trigger too quick and it jams. Speed load timing is way too fussy and is likely a part of the problem. This whole problem would go away if you would just get rid of the "jam" feature and just keep the trigger from doing anything until you are reloaded. It ruins this game.
