It is very important, than when the handguard is closed and locked, that there is some room for the locking mechanisme, as there is in the original Garand stock, which have a resess cut, in order to give some room for the trigger guard locking mechanisme.
For example, the "Ramline" stock, made of some plastic material, does not have that extra space for the handguard locking mechanisme, and a hole has to be drilled in the bedding of the stock, in order to give the "hook" some room, and thus avoid exessive, downward pressure, that during some of my shooting with the "Ramline" stocked Garand, releived the locking hook/spring, and to my horror, the whole trigger mechanisme ended up on the ground.
After carefull examination, I also found that the trigger guard/spring itself, has over the last half a century, losened up and become slacked, and few gentle pounding with a rubber mallet at the end of the trigger guard/spring, tighten the handguard/spring back to a much firmer grip
Also, I would strongly recommend to change the firing pin, if you have any plans to use your Garand for hunting, to ensure reliable use in the field. I also learned that the hard way
