I got 1301 for the same reason. I didn't want to miss out what some people kept saying is better than M4. It is much easier to load 1301 for sure, let alone double load and quad load. I can hardly imagine people speed-loading M4 in competitions! As for loading M4, I learned to keep my thumb fully bent and rigid, and use the forearm strength to load, instead of the thumb strength. I am not sure if I can still do so when I get order and have arthritis someday.
