I have a 4595TS carbine. I am trying to teach my fiancé how to use it. She is interested but she has zero experience with firearms. I have taught her safety practices while handling the carbine and she is doing very well. The problem comes when she tries to load the first round (practicing with snap caps in the mag). She has a lot of difficulty pulling the charging handle back all of the way to load the first round. Do you guys or gals have any advice that I can give her to make it easier? She pulls it about 3/4 back but struggles to get it all the way back to load the round. I have tried offering any advice I can think of but it still seems hard for her. Just curious. Thanks.
