Is there a significant advantage to Garands over M14s?
Most of the differences are debatable as to which is better. Sure the M14 has a higher mag capacity, but the Garand is one of the fastest reloading weapons in the world. As to an aside, regardless of what people have said, it is relatively easy to reload a Garand Clip in gun up to 7 bullets. It's an acquired skill to load the clip to 8 bullets out of the gun in a decently quick manner.
The M14 does have Automatic Fire. But since it is lighter, most except the bigger guys will have difficulty controlling it. The Garand is heavier.
Both incredibly reliable weapons, really accurate, and pleasant to shoot.
