Planning a trip to bench rest these two (if it ever cools off a little) and the most accurate gets to stay. The two I will be testing: totally stock Sig 1911 and a slightly modified Springfield TRP. Changes to the TRP, GI guide rod and end cap, mag well removed and steel firing pin. Both have shown to be accurate, but will shoot both with the same ammo off a sandbag. Winner stays and loser goes. Any guess ahead of time as to which one is the most accurate?
