I have a late production Remington M1903 and I'm having issues with the floor plate popping off. Any ideas on how to fix this? I was also having problems loading rounds into the magazine. It seems like the follower hits on the left side of the receiver and loading more than one round is either difficult or impossible and when I try to chamber a round it usually jams to the left and will not chamber. Lastly, seeings the proper trigger guard for this rifle was stamped, do I have the option of switching the milled trigger guard out for a stamped one. If so, are there any modifications necessary or would it be plug and play.

I truly appreciate any input as I am just learning about the 1903.
