Today I was at the range shooting a 1903-A3 and a Remington 1917 Enfield. Both in 30-06. No problem on knockdown or long-range power. THe 1903-A3 has the prettiest trigger pull. You pull back until it catches. Any increase in trigger force will cause the gun to fire. It is like this every time. I just wish it had a 1903-A1 rear sight instead of the 1903-A3.
I always rather liked the military trigger too, it seemed like it would never fire unless you really wanted it to.
The regular 1903 Springfield rear sight fastened to a pinned sleeve on the barrel, not on the rear of the receiver like the A3 model. The A3 therefore had a longer sighting plane. It was my preference.
