Relitavely easy "Gunslinger" trophy
If the Truck thing on Youtube isnt working for you...
Do everything normally then when Amsel is running line up a shot a couple feet ahed of him with the sniper rifle then switch to the pistol and fire at that location.
When I tried the truck thing it didnt work for me.
P.S. You get the pistol near the table near the missing wall right after the sniper battle.
