What about his lost trigger finger?
In Sniper 1 you clearly saw him losing his trigger finger. How do they explain his missing trigger finger in Sniper 2 and 3? Bionics?
shareIn S2, if you look, his right index finger is a snub and he is using his middle finger to pull the trigger.
shareBingo.
Also: at one point he describes himself as 'a four-fingered shooter whose eyes are going'.
